Excellent locatio, /staff & rooms
We booked 3 nights at the Sanctuary on Booking.com. Upon check in, Lucas at the front desk upgraded us from a Queen room to a King room. All the staff were very helpful and friendly. Location: This hotel is in a great location for holiday makers. Times Square is about 30 seconds away, Central Park is a short walk, there are bus stops and trains stops all nearby and Madison Square Garden is about a 10 minute walk. Amenities: The King room was extremely clean and nicely decorated. They had a turn down service every afternoon and the bed was extremely comfortable. The shower had a big shower head and the shower itself was of a decent size. 
Just a little bit of advice...we asked at the front counter if we could extend our stay for one more night. There was a young bloke on the desk who we had not seen before and he checked their availability and told us the rate for the one extra night. We decided not the book it with him as the rate seemed rather excessive, so we got on our laptop and booked the extra night on booking.com (which was half the rate we had been quoted at the front desk).
I would definitely stay at Santuary again when visiting New York.
