A clean room (that would just need to be vacuumed under the bed) in a house in a surprisingly quiet neighborhood. The neighborhood isn't bad but the street isn't the cleanest. A decent supermarket is nearby.
The bathroom and the kitchen are shared with two other rooms. The kitchen and the bathroom were clean. We didn't use the kitchen but it seemed to have all necessary equipment to cook.
The nearest subway is Gun Hill Rd. You can take the #2 to Manhattan. It takes 41 minutes (excluding walking to the station) to 96 street and 51 minutes to Penn Station. It was a bit far out for our purposes but that's of course no fault of the host.
The host was super responsive and accommodating.
