Great location, comfortable room
The Warwick is one of these mid-town hotels in NYC that once was grand, and remains an excellent choice in the mid-range of prices for Manhattan hotels (even though I have a hard time thinking of $300 a night as mid-range, but that's the reality in New-York). The lobby is beautiful, and retains its old time New-York glamour, complete with black and white pictures of long-ago movie stars. Our room on the tenth floor was surprisingly large by NY standards, with a beautiful, updated marble bathroom.
The room was impeccably clean, comfortable and well-appointed, though at first we could not get the heat below 80 degrees (the hotel sent in their engineer as soon as we reported the problem, and we were able to keep the room more comfortable the rest of the weekend).
The best feature of this hotel is its location, at the corner of 6th Avenue and 54th street. The walk from the hotel to Central Park or Bryant Park is just a few minutes, and Broadway theatres and restaurants are about ten minutes walk away. 
All and all we thought this was one of the better hotels we had stayed at in this price range in New-York City, and likely will be back.
