We loved staying in Mary's flat.
She was great to respond and help whenever I had questions before coming and her friend Taylor who was there to give us the keys was very nice and easy to get organized with.
Mary's place is awesome! It is clean, comfortable and very well situated in the UES. We were pleasantly surprised to see how quiet it was for a place in the middle of NYC. I would say that the only downside was that the living room/kitchen was a little dark (it looks onto a very small courtyard) but hey it's New York so we weren't home much! But the large bedroom has plenty of light (and the bed is super comfortable!) so it completely made up for it.
Thanks Mary for making our stay so lovely!
