We had a great stay in NYC in Kimball's apartment. The location for us was perfect because we were in town to go to the opera and concerts. Taxi to Lincoln Center cost about $7.50 and it is an enjoyable 20-block walk back after opera when the sidewalks weren't busy at night allowing one to 'come down to earth' after listening to great music.
Getting the keys was easier and faster than checking in a hotel, and communicating with Kimball worked splendidly.
