I am a frequent visitor to NY and I loved my stay at this apartment! I would highly recommend this rental.
First two caveats: It is "newer" and not "new." It suffers from a bit of wear and tear. Having said that I was amazed at how comfortable the bed was (better than in most luxury hotels I've stayed in) and all the furniture/appliances were in good to excellent condition. Also while I would say the apartment has plenty of hanging storage it could use some more nonhanging storage (for underwear, socks, sweaters, etc).
Aside from that this place was perfect. I loved the location. It was convenient to the UWS, UES, Midtown or anywhere else in the city. It was truly quiet (a major surprise given how busy the street life was in front of the building!). The balcony was just amazing with both a backyard garden and urban view. It had a table and two chairs and I had breakfast there most mornings. The internet service was excellent.
Lastly, Eran was very responsive. I had a few questions and he always got back to me in a reasonable amount of time.
