Great, clean place, quiet and peaceful surroundings.. Amenities as described and room space is bigger than most in the city.
A bit of walk from Shinagawa station, but Shinagawa station itself has direct access from both major airports and has direct train lines to all major stations in Tokyo (Tokyo st., Shinjuku, Shibuya, Ueno). Shinkansen trains also go through Shinagawa, so super convenient if you want to move to other cities.
