I had a nice experience staying at Wayne's. Unfortunately I only got to meet himself for one day, but there was another person there supervising the appartment that was very welcoming as well.
The appartment is conveniently located in Harlem, in short walking distance to several Metro stops. The neighborhood is lively, but can get a little noisy at night.
The room and the kitchen/bathroom was very clean and tidy.
You will be sharing the appartment with other guests and the stairs/floors make quite some noise. If you are a light sleeper, that might not be optimal for you.
