Deborah's apartment very comfortably slept me, my partner and daughter. Everything was very clean, the beds were really comfortable, the pantry in kitchen had a few non-perishable necessities provided for if we wanted to cook at home.
It's also really light for an NYC apartment - because it's on the top floor of the building it has a couple of skylights, and there are also really nice views out both bedroom windows of row houses and their gardens, with lots of trees - very peaceful and quiet.
There are loads of places around to eat - we went to Ess-a-Bagel on First Ave most days, for great bagels and coffee. The L train is a less-than ten minute walk away, there's a laundromat (not self-service) around the corner, and it's a 15 minute walk to Union Square. Recommend Friend of a Farmer for a (not super-cheap, but yummy) lunch. Gramercy itself is a great neighbourhood - interesting places to eat and shop, and it felt really safe - we often got the L train back to First Ave around 10pm, and then walked back to the apartment and had no safety issues.
Deborah was a thoughtful and considerate host - helpful with suggestions of things to do, but not intrusive, and quick to reply to messages. We couldn't have asked for a better place to stay for three weeks in New York, and highly recommend Deborah as a host, and her lovely apartment too!
