I've been living in PC for a few months while my new apartment gets renovated. (Note: PC is very popular for this; a high proportion of the guests here seem to be New Yorkers between homes.) You can rent a studio, one, or two bedroom (all with a kitchen) by the month or even the week. They're flexible about extending leases. The rooms/suites are stylish, modern and comfortable. Great big flat-screens, bose sound system, nice kitchen and bathroom. My one-BR is also pretty quiet, which is nice. PC's location is terrific, not just for Lincoln Center and all the conveniences nearby, but also it's a block away from the 1 and 9 train and several Broadway bus lines. What I like the best about this place is the staff. The doormen, desk people, housekeeping and maintenance people, they all give top-notch service. They have been unfailingly friendly and helpful. The minute you have a problem, they are on it. They can arrange anything - car service, in-room massage, dry cleaning, messengers, show tickets, you name it. I feel very well taken care of here and I recommend it highly to New Yorkers and to visitors.
Pros: Terrific service, amenities, ambiance and location
Cons: It's expensive. And cell phone/wireless reception in rooms is sketchy.
