Reviews

Former tenant·1 minute ago

Good neighbors, surprisingly quiet

Pros

Building was well maintained with a highly responsive super. The unit was shockingly quiet despite living just off Broadway. Neighbors were great and I felt watched over coming in and out of the building. Transit access is the best I've ever experienced in NYC. Close to so much greenspace, including riverside access. Unit was newly renovated when I moved in.

Cons

Landlord was only average level scummy, my unit was owned by a faceless company that bait and switched my security deposit to a broker fee at lease signing, knowing I was in no position to walk away at that point. Management company was non responsive to concerns, although this barely impacted living conditions since the super was incredible. Slight roach problem in the basement and lower floors. Occasional pest in the 5th floor unit.
