A tastefully furnished apartment in an amazing location. Where else in Manhattan can you sit outside, not facing the street, and actually look onto trees in a garden? (We stayed in the Terrace apartment, not sure if the others have this too). The management is very professional and extremely helpful - the owner was able to provide us her own long-serving trusted nanny to babysit for us. The conditions might appear a bit restrictive at first, especially if one has stayed in similiar accomodations across the world, particularly in Asia, but then one must realize that the market for this type of accomodation is still evolving in the US - and besides there is really nothing in the conditions that is unreasonable.
We were not bothered at all by the rehab center next door - in fact if not for having read other reviews we would not even have noticed it! There was no street noise whatsoever once inside the apartment - you can hear people moving up upstairs but it is quit muffled.
We look forward to another stay very soon!
