Reviews

Former tenant·9 minutes ago

Generally pretty great

Pros

Pretty responsive management, super and porters are extremely lovely people, generally clean building

Cons

We had roaches throughout our tenancy, and needed to self-mitigate while also signing up for the exterminator. 2 mice incidents due to shotty construction and blocking under sinks and cabinetry.

Advice to the owners

block and plug any under the sink cabinetry and pipes to keep rodents out.

Nice pre-war rental building in the Heights

Pros

Great neighbors. Friendly and responsive super. Beautiful spacious apartments in a fantastic location. Good value. Clean and well-maintained compared to similar buildings in the area. Nice laundry facilities in basement with plenty of machines here and next door at 620.

Cons

Minor pest issues. No central amenities like outdoor space or rooftop, in-unit laundry, or storage. Noise from Fort Washington Ave.

Advice to the owners

Manage pests more aggressively.
