Great space with very clean room and bathrooms. The only reason I can't give it 5 stars it's because of the location. It's quite far from all the touristy things to do in Tokyo so unless you don't mind the hour of transportation both ways, I would try to find something closer to Tokyo.
Otherwise, it's a very nice place to come home to at the end of the day. There's also a 7-11 and Family Mart super close. Definitely a plus if you're traveling during typhoon season like we did and had to stay inside for a night lol.
