We (my spouse and me) had a wonderful time in the penthouse of Ari. It is very spacious, well equipped and very cozy. It's full of light and in reality it looks even better than in the pictures. It's by far the best apartment we have ever rented in NYC. We didn't meet Ari personally, but the communication with him was very easy and he fulfilled any request we had.
We definitely recommend it to other persons (hoping it'll be available next time we come to NYC...).
