My wife and I stayed in Jianren's apartment for two weeks. I would agree with pretty much of what has already been said - the location is great, right on the M subway line (and close to the L line), lots of places to eat/drink in Bushwick close by, apartment is spacious, there are air conditioners in living room and both bedrooms, communication with Jianren was easy/fast. The kitchen utensils/silverware are very sparse, the beds appear to be doubles rather than queens (not a problem for us since there was only the two of us). The subway noise did not bother us but you are right next to the elevated track. I would definitely stay here the next time we come to Brooklyn.
