Reviews

Former tenant·just now

Mouse issue not taken seriously

Pros

Clean, nice neighborhood

Cons

There was a mouse issue that the owner was severely negligent about. The in building washer dryer was also always broken and it took about 5 emails and calls from several residents for him to address it, only for him to give it a shoddy fix so that it broke again a few weeks later. Not only that but he increased the cost of the w/d even though the issues remained the same.
