It was a great place to stay. Lovely neighbourhood with plenty of amenities nearby. There are a few city-bike stations within 1-2 blocks, which is a great way to explore Manhattan.
Doug was very helpful and relaxed. He wasn't in when I arrived, and he had arranged the neighbour to let me in.
Only downside to this place, it's at the top floor. And since the building does not have an elevator, you do need to climb several stairs. Which in itself is a nice exercise :-)
