Great location near campus, makes getting to class super fast and easy. It's also nice to a gym and pool right on the property. Super happy with my apartment here and looking forward to living here another year.

Not worth your money.

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.

Luckily, the garage's spaces are assigned so you should not be experiencing any further... issues with parking easily. We are not owned by \"five star\" but are disappointed that your standards were not met. My team and I are actively working to correct any outstanding issues and will continue to ensure Union 9Seventy is valuable, comfortable, and the best place to call home.
