The Park Hyatt global flagship in the base of Extell's One57—the super-tall luxury condo building rising just south of Central Park—is accepting reservations for as early as July 20, earlier than the previously reported Aug. 28. Last week, we took a hardhat tour of the luxury hotel. (Not even the Hotel Tonight app gets you this kind of access.) We snapped our hosts, Park Hyatt New York's Lynne Bredfeldt and hotel GM Walter Brindell, who tell us a limited number of the 210 rooms will be available in late July and most by late August, and earlier days may become available. (This year's opening also coincides with Park Hyatt Tokyo's 20th anniversary and the opening of Park Hyatt Vienna.) Lynne tells us the property will serve both business and leisure travelers, but international travelers will form a big part of the biz.

The hotel will occupy the first 25 floors of the 90-story building. Rooms average 530 SF and start at $795/night, and suites (92 of the 210 rooms) go for as much as $1,495. The property also will be pet friendly at the urging of Walter, who's got two dogs of his own (Papillon mix Rocco and Corgi Emma) and is an active supporter of DC's Washington Animal Rescue League and a member of the board of PAWS Chicago. We hear some luxury canine amenities will be announced soon. (Shiatsu for Shih Tzus?)
