This is a fantastically located hotel, directly across from Shinagawa, so its easy for a weary traveler to access. Its not marked well, though, so you have to look carefully for the sign as the hotel is within a nondescript office building.
The staff is very courteous, and the facilities are fine. The room was somewhat small but efficient, and the breakfast was acceptable for business. Because of the location, one could easily hope on the metro to get anywhere in Tokyo. But, there are some nice restaurant gems within walking distance of the property.
