Reviews

Former tenant·Over 1 year ago

Terrible building to live in

Pros

Located next to an elementary school so the park with trees is a nice view from the windows.

Cons

Consistent heat/AC issues, huge Mice problem, building leaks consistently in the hallways and within the units. Roof has leaking problems that they have been trying to repair for months and the issues persist. Exposed brick is not taken care of so it crumbs everywhere.

don’t do it

Pros

laundry in building lots of cats outside

Cons

management are negligent. i’ve had a bathroom ceiling leak off and on for THREE MONTHS that i have to call about 5-6 times per “fix” to get sorted. the plonking of rotted rain water into a nearby bucket is the soundtrack to me writing this review. heat is turned up to unbearable temps in the winter. my dishwasher didn’t work for the first 3 months i lived here. every “fix” made to a broken or problematic fixture in the apartment is poorly done and shabby looking. had an ant issue over the summer that i had to deal with entirely on my own. had to deal with a roach or two. no nice here but neighbors got some. just a very difficult place to live, it’ll feel like an additional job trying to get everything running as it should.

Advice to the owners

just do better. be responsive to your tenants, provide weekend assistance for key issues
