We booked the Mark as a diversion from our usual hotel on the West Side of NYC based on its web site and reviews. It is a truly luxurious venue. It is a nice size with no convention traffic and the rooms are quiet and restful with all the expected amenities (we especially liked the abundant ice in the freezer compartment). We were offered the hotel car for a complimentary trip to the Opera. The staff are efficient, courteous and promptly responded to our requests to clean the room at a certain time. All in all, we feel we have discovered a new favorite in NYC with access to Madison Avenue and the museums of the upper east side. Not inexpensive but for us it was worth the price.
