We stayed here for 6 nights in July. Although we didn't meet Ari himself, we had Aleksander welcome us to the unit. Aleksander was lovely, very helpful with tips on where to dine etc. in the neighbourhood. The penthouse is wonderful, clean and very spacious for New York. Decor is a lot of old fragile and precious things of Ari's. The Rooftop Deck is fantastic. This unit well and truly exceeded our expectations. Only downside would be that the floors are creaky in the bedroom - this may have bothered us more than most as we had a baby with us. Otherwise I highly recommend this Penthouse.
