Tina was a great host! Unfortunately, we didn't get to meet her, but everything was set to make us welcome from day one. She was always helpful, and answered all my questions in little time.
The house is very nice, big enough for two average families or a large group of friends, and the three toilets (one per floor) are really useful.
The neighboorhood is quiet, (which for me is a good thing in a frenetic city like NYC), close enough to the rest of Manhattan using the subway, and in a few minutes of walking you get to a big street full of stores, and some good places to eat.
Everything went good, I'd suggest Tina's house, and I'll remember it if I manage to come back to New York!
