Clean hotel. It is NOT a self contained hotel building. It is part of a larger set of business offices etc. It is basically an upscale business hotel. So, expect what you would see in most Japanese business chains like Toyoku Inn and Alpha in terms of room size, but you are paying 100 to 200 dollars more. Not sure why. King size bed is more like a double size bed. Not much walking around space in the room. Expect loud train noise coming from nearby Shinagawa station. you will need a taxi (4500 to 5000 yen to haneda airport) to get to nearby things--700 yen to shinagawa station. There is a free shuttle that will take you to Shinagawa station but this hotel does NOT have a shuttle to and from the airport. A final positive note: There is no lobby. The "lobby" is the restaurant. However, a staff member allowed us to hangout in the executive lounge on the 25th floor for a couple hours after check out since our flight did not leave until 5 PM. That was nice. If you got cash to blow and there is a mystique about staying at a marriott, then go ahead and stay here. But, truth be told, you can basically get that 350 dollar double room for a hundred dollars at Alpha or Toyoku.
