Fell Short of Expectations
My wife and I just returned from a one night stay at the Sofitel New York. Overall I came away with mixed feelings.
The location in mid-town is very convenient to everything within the city. The SoBed! Probably the best feature of the hotel is the bed, or as my wife called it, the Cloud. 
The staff however was quite a disappointment. Despite the fact that we were greeted upon arrival and escorted thru the lobby to front desk, service failed to impress beyond that. Check-in was fairly robotic and we were soon on our way up to our room; Luxury King was booked. The room itself was quite spacious by New York standards but we felt that the use of space poor. The room and facility as a whole felt like it was beginning to show some wear and tear....for some reason they taped duct-taped down the mats at the entry hall as well as at the front desk - this gave off a very janky vibe, not respecting of a 4 or 5 star property. Interaction with staff, from room service to the bell staff seemed very cold and uninviting; response time for requests however, was very quick.
All in all, I'd be hesitant to recommend the Sofitel New York. Having stayed at the Sofitel DC a couple of years ago, I had much greater expectations that were brought down by uninspiring staff and mediocre condition of the property. 
Safe Travels!
