Those in the know instantly recognize this Upper East Side hotel’s geometric black-and-white striped marble flooring. Whimsical in design but rooted in French elegance, The Mark Hotel, designed by Jacques Grange, has incredible artwork and objets d’art throughout. There are gourmet picnic baskets, a chauffeured The Mark-branded pedicab, custom bicycles and a private sailboat, The Mark Sailboat. It’s also home to the US’s largest suite, a penthouse on the 16th floor that clocks in at 10,000 sq ft. It has all the luxuries of a residence, and then some, with five bedrooms spread over two floors, a living room with 26-ft ceilings, conservatory, library, lavish dining room, private rooftop terrace overlooking Manhattan and outdoor dining space made for entertaining.
