My family stayed in two rooms next to each other (couldn't get adjoining) on the 20th floor over the past few days. The smallish rooms smelled of smoke and much of the furniture looked like it came from the 50s. The front desk and bell personnel were very nice and helped us get a portable router in our room so we could use our wifi devices. The location of the hotel was good as we needed to get to various places in Tokyo, but it is not a leisure area (across from Tokyo Metropolitan Government buildling).
The staff are used to helping foreigners, and there seemed to be lots of tour groups at the hotel. The Limo Bus from Haneda stops here so that was very convenient.
There was an advertised exercise facility, but my daughter discovered it was actually a former room with a few pieces of exercise equipment - which was not air conditioned. There is a pool but it is 2000 yen per person to swim.
I would not stay here again nor would I recommend this property.More
