We were there for the second half of our trip to Japan, and are already talking about coming back. It was soooo convenient being attached to Haneda airport, with access to transportation. The availability and variety of shops and dining was amazing. The hotel was clean and the staff were very helpful. The hotel restaurants were delicious. We ate at the daily breakfast buffet and their premier dining. We also visited several of the dining in the adjacent shopping area. The spa is amazing. I used the Onsen and the stone massage. The onsite Onsen was an amenity that influenced my decision to stay here.I can also verify that they are tattoo friendly. Which is not the case at many other Onsens.I don't have any that could be considered offensive or gang related, which they vaguely refer to in the Onsen policies. We purchased the breakfast package which gave us each 1 voucher per day to the buffet. We purchased the spa package which gave us access to the Onsen and spa dining, massage and other spa procedures are extra (very reasonably priced). It was more expensive than our stay in Okinawa, but definitely worth every penny. My room overlooked the Monorail and the airport. I could literally watch planes take off and land from my window. Other reviews mention hearing the airport noise, but I heard nothing. Not even from adjacent rooms. They have eco friendly cleaning schedules. The water pressure was amazing and the shampoo/conditioner smelled great.
