Union 9 Seventy has been incredible so far! Communication is top-notch — every email and phone call I’ve made has been answered promptly, which is such a breath of fresh air compared to other places. Grace has been absolutely amazing to work with, and the entire front staff is friendly, professional, and helpful. Although expensive, the property itself is beautiful and well-maintained despite somewhat dirty hallways, and I’m genuinely excited to live here this school year. If you want a place... with great communication, a welcoming team, and a stunning property, Union 9 Seventy is the way to go!

It's going pretty good so far! Although, I have only lived here for about a week so far. The staff is great and have been very helpful with move-in.

Just moved in- The move in process was very organized and the Union team did great with making it smooth and organized. The only issue was the trash was overflowing in the garbage shoots

Thank you for taking the time to leave your feedback! It's great to hear move-in day went smoothly. Thank you for your patience with our team as we work to keep up with the higher-than-normal volume of trash we experience during move-in.

The apartment was not cleaned when we moved in and a lot of things are broken or in disrepair. The staff, however, are very kind and do their best to be helpful.
