Reviews

Former tenant·9 minutes ago

A nice spot accross the park

Pros

The building has that pre-war charm with many original details intact. Manny, the on-site super, is friendly, responsive and easy to work with. The landlords are relaxed and don't come around too often.

Cons

The landlords are not super involved and capital improvements can be sparse in some units.

Building Review for Prospect Park West

Pros

Nice neighbors, gorgeous roof, nice hallways. Bins for garbage. Monthly optional exterminator service. Right by the park!

Cons

The Super lived in the building but was hard to get ahold of, repairs were put off for extended periods. Rent checks had to be mailed. The heat was inconsistent and it got very cold in the winter at times. Water temp also fluctuated a lot. The water went out for several days due to nearby construction, not the landlords fault but they failed to warn us or provide any information about it. Packages often stolen.

Advice to the owners

Some way to pay rent and submit complaints online. Or just being more responsive to texts / calls.
