My wife, our three sons (ages 7, 5 and 2) and our babysitter stayed for 5 nights in this wonderful apartment.
This would be a great space for adults only but it's also an amazing space for adults traveling with children. (The owners have a child, there are toys, etc., and my boys were thrilled!)
The apartment was super clean and they supplied wonderful linens and other basics. The location is great -- quiet enough and close to Riverside Park but also very close to the subway for easy access to essentially anywhere in Manhattan.
Joel was incredibly responsive to any/all questions I had before and during the trip, and generally could not have been a better host. In short, I can't say enough good things about this apartment. We would absolutely stay here again!
