Reviews

Former tenant·Over 1 year ago

Worth it for the rent price

Pros

For a NYC apartment, it was spacious for the rent price. My unit was renovated so the bathroom and kitchen was decent. In building washer/ dryer (2 washer/ 2 dryers).

Cons

The tenant on the 6th floor (6G) was always playing loud music, fighting with his girlfriend or making noise at 6am. The super didn't do much about it. The lobby and staircase could have been cleaner.

Mixed Feelings

Pros

The super Ernesto is great, the building stays pretty clean and they manage the garbage very well.

Cons

My upstairs neighbors were horrible, they kept me up all night and threatened me and escalated things when I continuously asked them to stop stomping on the floor throughout the night.

Advice to the owners

I don't know what they could have done about the neighbor situation. I eventually moved because of them.
