Reviews

Former tenant·Over 2 years ago

Excellent landlord and management company

Pros

It’s well maintained and it’s not loud inside. The super comes next business day in most scenarios. Things get fixed within a few days.

Cons

If you break something, the Landlord may not fix it and make you pay for it
