I had a great stay at Anthony's guesthouse- everything was spotlessly clean, modern and comfortable, and the apartment was very quiet- almost no street noise- a rarity in NYC! Anthony is a gracious and responsive host.
Only downside was it is in a slightly sketchy neighborhood, and the doors to the apartments are thin so everything that goes on in the common area can be heard in the rooms.
Overall though this is a fantastic place- would stay here again!
