This was a good value for NYC and we were lucky to find it super last minute only a week before arriving (other comparable places seemed to be going for at least 2x the price). The room was clean and comfy with its own patio area which made it feel more spacious. Cornelius and Manuel were super responsive and kind, and check-in was a breeze. The location is close to a few subway lines (<10 min walking) including one that goes to the airport. It's not too far out in Brooklyn which made it easy to get everywhere we wanted around the city. For these reasons, I'd stay here again.
There are a few things I think others should be aware of before booking to make sure it's the place for you. These were not dealbreakers for us but may be for others:
1) The common areas (kitchen and bathroom) are shared with 2 other rooms and don't seem to get a thorough cleaning between guests due to the staggered bookings (for example, there was a pan with food remnants left on the stove for the 3 days that we were there). If you do not plan to use the kitchen much and will spend most of your day out and about, it shouldn't be too much of a bother. We understand the host may not have total control over what other guests do and how tidy they are, but a more frequent cleaning schedule for these areas might help.
2) We stayed through part of the weekend (Fri night) and the building did get loud with music and people coming and going on the stairs. Caveat being this is NYC and many other apartment buildings are like this too. The apartment itself and other guests were quiet and weekday nights were quiet but if you are staying for the weekend and are an early and light sleeper, this may not be the place for you.
