Reviews

Former tenant·Over 2 years ago

Old and loud

Pros

Rent stabilized… that’s it

Cons

Weird neighbors. The wood floors are extremely loud. You will be able to hear every movement in the unit above you. Walls are extremely thin. Pest problem.

Advice to the owners

Paint the inside of the apartment and upgrade the buzzer. Make sure tenants are compliant with the 80% carpet rule.

Former tenant·Over 2 years ago

2 Year Tenant

Pros

Super quiet, very safe building with great neighbors. Super and Landlord for our unit specifically were both great as well. Charming courtyard and interiors, and incredible location!

Cons

Quite an issue with cockroaches and mice. Building’s old and thus it’s more or less expected, but at one point it got so bad that we’d considered breaking our lease.
