We stayed at the apartment for 5 nights. There were 2 couples and a one year old. The apartment was perfect for us. The location is excellent, in a quiet area but very close to lots facilities - subway, cafes & restaurants, grocery stores, even the 'High Line'. Chelsea is a lovely part of New York and you are within walking distance of some other lovely areas.
The apartment is quite large by New York standards and for us was so much more preferable than hotel rooms. The kitchen has everything you need andthe loung area is good for relaxing. At no time did we hear street noise. The apartment was very clean on our arrival.
Cayla was terrific to deal with, so professional and accommodating. We even got a text from her during our stay. I wish there were more hosts like her. She even arranged to leave us two sets of keys.
You stay on the third floor but carrying luggage up was no problem.
I would highly recommend this apartment and the host to you.
