Former tenant·just now

Very Pleased Overall - 3 year tenant

Pros

Location cannot be beaten for the price. I pay 2250 for a rent stabilized one bedroom unit. It is right in front of Prospect Park and Parade Grounds. The area is maintained very clean. This cannot be overstated, since the surrounding area in Flatbush can be somewhat dirty. The building is very clean and the neighbors are great. Very close to the Q/B and relatively close to the F/G. I would not leave if I didn't have to.

Cons

Parkside Ave is a busy street that feeds directly into the BQE. As a result, the street is generally always busy with cars, lots of traffic, and lots of people revving their engines/loud car music/ambulances. I would say it was more prevalent than other neighborhoods I've lived in (Bay Ridge and East Harlem). My unit is alley facing so I didn't deal too much with the noise, but if you have a park facing unit, I imagine the noise could get annoying.

Advice to the owners

Never really had an issue with the super or owners. They are generally very responsive, except for one repair that I've been asking to be fixed, but it's more aesthetic than habitability related. Therefore, not much to complain about.

Good location, large spaces, fix the issues incl the crap neighbors

Pros

- large spaces, high ceilings - across from park

Cons

- Building front door has been broken and unlocked for almost 2 years, with management saying 'it's gonna be fixed'. Some days it's literally swung open for hours at a time.Packages stolen constantly, homeless folks coming in and out to sleep on roof, no security. - A lot of good folks in the building, but a couple of a**holes ruin it for the rest - loud, inconsiderate, obnoxious... play loud music all hours of night and day, have loud phone calls at windows and courtyard for all to have to listen to. - Floors are old and very thin - can hear everything from your upstairs and downstairs neighbors - can hear full phone conversations, tv, music - Units don't get light unless higher up. - Management company does nothing to address issues.

Advice to the owners

- Deal with the a**holes in the building - Fix the front door already
