I stayed at Kimberly's house for few days and the whole experience was great, it''s been the perfect combination between costs, location, privacy, cleanliness and attentive/flexible host.
the Room: actually it's a sort of studio because of the private bathroom and the separated entrance, there is a window and the yard backdoor so you don't feel to be "in a basement"; the kitchen is upstairs i didn't use it and u won't if you stay in NY for few days..anyway it's a full big kitchen.
Location: easy to find, convenient to reach from JFK, at a walking distance (10mn) from the B and Q express subway train (7Ave) that leads to Midtown Manhattan in 25 mn, less to Downtown.
Neighborhood: very safe at night, many bars restaurants and deli around.
Host: Kymberly has always been reachable by phone and her housemate Anna has been lovely too, the kind of person you would have as housemate.
I would definitely come back next time i need a place for few days in NY.
