The apartment is wonderful. Perfect for 2 couples. I think we could have added another person/couple into the main bedroom, but I would only recommend that if you are comfortable sharing personal space. We only had 4 people, so it was fine anyways. The apartment is spacious, mostly bedroom. The kitchen had all of the tableware/basics that we needed. Plenty of towels in the bathroom. Everything was clean. It was unseasonably warm, but the window air conditioner units worked well. The only critique is that the mattresses were quite loud, and could probably be replaced. But we were comfortable and happy even with the squeaky springs.
Adrianne was there to meet us when we arrived, and was very sweet. She was always quick to answer even the silliest question. She was a perfect host!
We absolutely loved staying in Harlem. The 2/3 subway line is a 5 min walk, and it was the only line we needed. We went to Statue of Liberty, Midtown/Times Square/Broadway, Central Park, all very easy to get to. Harlem itself was great, there are amazing bars and delicious restaurants. We were a 5 min walk from a grocery store that had all we needed.
The apartment was quiet, noise was never an issue. We would definitely stay there again.
