Let’s start with the positive:
Location in Cobble Hill is great, you can walk to the subway (15 minutes) or to the bus station that is very close (5 minutes). Plenty of good delis, bars, restaurant in the vicinity. The apartment is well equipped, esp. the really huge TV screens both in the bed and living room are cool. Cleaning quality is good, the apartment is not really renovated, but in a okay-ish state. I got a good rate compared to other offers in the area, so a little bit of compromise in terms of quality is acceptable.
The downside:
A busy street and the Interstate are directly in front of the apartment. There is a lot of street noise day and night, esp. as the insulation of the windows is lousy. It is a bit better in the bed room, but I still needed ear plugs.
And then the check-in process: While the host was not flexible in terms of check-in time, I had to wait at the time he suggested nonetheless for more than hour in front of the building for the check-in process to start, because the cleaning lady apparently still had the key.
