Bordering the university’s main campus, Baseline Sub is home to the University of Colorado Boulder East Campus. The university dominated the northeastern corner of the neighborhood, giving the area a youthful, park-like vibe. Staying true to Boulder culture of sustainability, Baseline Sub has several parks, bike corridors, and while trails that weave through the Boulder Flatirons are less than 15 minutes away. There are multiple large shopping plazas, restaurants, and breweries directly north of Baseline Sub, so residents have plenty of amenities close to home. For more variety, especially with nightlife and entertainment, many residents head to University Hill and Downtown Boulder, which are both about two miles away. Although Boulder is known to have upscale properties, there are more affordable options available as well. When searching for your next rental, you’ll find houses, apartments, condos, and townhomes.

Property Ratings at Union 9Seventy
The community is great! They do tons of fun event and I love the engagement. The layout is really pretty and I like the views. I do wish they would fix the garage door.
It’s pretty okay, the sinks and bathtubs don’t work very well but everything else is good. SOOOOO expensive for what it is though. nice place to live
Property Manager at Union 9Seventy, Responded To This Review
Thank you for sharing your feedback! We're glad to hear that you find Union 9Seventy a nice place to live.

If you ever have any concerns, please don’t hesitate to reach out, and we’ll do our best to address them promptly.
Expect the bare minimum. Hallways are always messy and they don’t clean them. When I was moving in it seems like they didn’t inspect the apartment at all as I had a dresser full of random peoples clothes and it was destroyed and the whole apartment was not clean (they would rather give out $50 gift cards to people than pay to clean the apartments). The price is outrageous for the laziness in here they give slumlords a run for their money. You also pay for every utility, internet and parking and good luck finding a parking spot here because it’s either spend 3 hours looking for a parking spot or $120 a month for parking. Would highly not recommend living here and look for something not owned by five star as they have this reputation.
Property Manager at Union 9Seventy, Responded To This Review

If you have any further concerns, I kindly urge you to email me directly: union9seventymgr@greystar.com. Thank you so much for giving us this opportunity to improve your experience.
Everything is solid so far outside of a few minor hiccups. The pool being shutdown is a little bit of a let down, since us residents paid to live in a complex with a pool.
Property Manager at Union 9Seventy, Responded To This Review
Thank you for sharing your feedback! We’re happy to hear that, overall, you’re enjoying your experience so far. We completely understand your disappointment with the pool being shut down, and we sincerely apologize for any inconvenience this may have caused. The pool has since been closed for the season but will reopen in the spring - we hope to see you there! If you have any further concerns, please feel free to reach out!
I love the apartment lots and lots! The pool and elevators could be cleaner. The door to the stairs from the outside doesn’t lock which is kind of dangerous.
Property Manager at Union 9Seventy, Responded To This Review
Thank you so much for your kind words! We’re thrilled to hear that you love your apartment. We also appreciate your feedback about the pool, elevators, and the door. We’re happy to let you know that we’ve addressed the door issue, and it is now securely locked.

The apartment is great and have mostly everything available in the move in date, there were no big issues and the view of the bedrooms are great. Also it has a great location near the university.

Hello, we strive for 100% satisfaction, and it is great to see you had such a positive experience at Union 9Seventy.
Beautiful place and love the area :) Little noisy occasionally, but that’s to be expected in a college town. Really close to campus, and it has a patio!

Hello there, we appreciate you taking the time to leave us this feedback! We're thrilled you're happy with Union 9Seventy!
maintenance orders take a long time to get filled. many things were not working in our apartment upon arrival. union apologized but it doesn’t matter. our shower, and dishwasher do not work and there are bees on our balcony
Property Manager at Union 9Seventy, Responded To This Review
Thank you for taking the time to share your experience. We sincerely apologize for the maintenance issues you've encountered, and we understand how frustrating this must be. It’s certainly not the experience we want for our residents. Your comfort and satisfaction are important to us, and we appreciate your patience while we work to make things right. Please don’t hesitate to reach out directly if you need further assistance.
So far I have had a good experience here at Union 9seventy. One thing that I think could have made the experience even better would have been having more communication about matinence requests. As well as a little bit more detail when it came to how clean the apartment was before move in. Other then those things, I have loved all the amenities as well as the quality of my apartment
Property Manager at Union 9Seventy, Responded To This Review
Thank you for taking the time to share your experience with us! We truly appreciate your feedback regarding communication around maintenance requests and the cleanliness of the apartment before move-in. We understand how important these aspects are, and we’re actively working to improve in these areas. If you have any further concerns, please do not hesitate to reach out!
Only reason it didn’t get 5 stars is because we’ve had multiple maintenance requests put in since we moved in three weeks ago, and none of them have been addressed. Apart from that, I love the community. The location is amazing, and the apartments themselves are very nice.

Wonderful amenities and friendly neighbors. Everyone always says hi when you walk by and holds the door open for you. The employees in the leasing office are very kind and helpful as well.
Property Manager at Union 9Seventy, Responded To This Review
Hi, we are very happy we could provide you with a positive experience!
I have lived here for almost 8 months now, and I have had nothing but great experiences. While the cost is very high, it has been worth it thus far. The apartment, appliances, and furniture is new and well kept. The package room is secure to ensure safety of packages, and the garage has been wonderful for my car throughout the winter.
Property Manager at Union 9Seventy, Responded To This Review
Hi, your review about Union 9Seventy made our day! Thanks so much for taking the time to write.
Seriously horrible. don't live here. Incredibly unsafe -- trust me your car is not even safe in their garage. Im just shocked at how unprofessional the staff is -- I pay so much for nothing. The location is not worth it. The walls are paper thin, the place is a mess, ac barely works, doors barely work (idk who put those doors on), garage is unsafe and designed horribly. if someone is in your spot in the garage (which you have to pay over $100 for) then the best they can do is put a little sticker on the car saying your in someones spot. they say they can tow but I've heard they can't. beware of this place, just don't live here - seriously.
It’s horrible. The garage is very unsafe, the heating barely works, they barely clean the place or throw out trash. I saw a bowl of soup spilled near the mail room for weeks. Over priced. And the management is horrible. They don’t care and they just want to make a profit. They are full of false promises. Don’t trust the garage or even the package room. The package room is a mess with packages everywhere and 20% of the packages get thrown into this box and if you don’t pick it up within 3 or 4 days (not sure but less than 5 days I think) then you get charged $3 each day it’s in the box. And sometimes the system is not accurate and you will just get charged even though you picked it up. Everything is horrible and made horribly. The garage was horrible designed and the garage door gets broken a lot.
Lived in a 3bed 2 bath and had an amazing experience! The building is brand new and shows it. Compared to the old run down places of Boulder, not having leaks in the ceiling or bug infestation is definitely worth it. Not to mention the high security and private garage that give me some peace of mind at night.
