OK, let me be the first to kick off the review thread for what many regard as the finest Hyatt hotel in the world. When the PH opened 15 years ago, it was the only modern luxury hotel in Tokyo. Now it has a lot of luxury hotel competition (which presently is keeping Tokyo luxury hotel prices amazingly affordable by international standards), but it remains an outstanding hotel. The hotel is located on the 39th to 52nd floors of the Tokyo Gas building in west Shinjuku. It is about a 15 minute walk from Shinjuku station, and has been criticized for this, although the hotel runs a free shuttle service for much of the day every 20 minutes. There is a second free shuttle service every 10 minutes to/from another part of the same building, and a 100 yen bus service to/from the station every 10 minutes that stops right in front of the hotel. Entry is via lift from the 2nd floor entrance. The lift can make only two stops: 39 (used for banqueting business, which is nice, since it separates all these folks from hotel guests) and 41, the entry level. The lifts open onto the Peak Lounge which also serves a nice "one plate lunch" at noontime. Other hotel restaurants include Girandole (French) on the 41st floor, Kozue (Japanese) on the 39th floor, and the New York Grill (guess!) on the 52nd floor. Rooms start at about 40sqmt. The smallest room is the Park King; the Park Double is actually a bit larger. I would skip these in favor of at least the Park Deluxe, which is an excellently laid out and designed room about 45sqmt in size. Above that is the Park View, which used to be called the Corner King. All rooms have stunning views, either out over the center of Tokyo or in the direction of Mt. Fuji, but most days Mt. Fuji is obscured by clouds. The hotel has a large number of additional features that are not readily advertised. They will loan you a mobile phone while staying there, charging only for calls made. They will loan you bicycles for free. The swimming pool on the 45/'46 floor along with the gym has to be seen to be believed, but treadmills may not be good if you are an agoraphobic! I know a fair amount about this hotel, having stayed there many times, so would be happy to answer questions.
