Location is fantastic. 3 minutes from the Nation Art Center, 5 minutes to all subway lines, Tokyo Mid Town, Roppingi Hills and amazingly, surrounded by pretty cozy and calm neighborhoods. Takayasu is such a responsive host that he reacts whatever message you send to him within a minute. The washing machine was so convenient. It is noiseless and one stop process till drying without an wrinkle. All the necessary detergent and softner are set up and you just need to push the button.
A couple of caveats. As other reviewers pointed out, the stairs are narrow and steep (especially to room 3). So if you are bring large suitcases or have problem with your knees, this place would not fit you. Second, This room has two double beds, but one bed has hollowed springs on the bottom right side. We were 3 members but 4 people look tough. Third, there is a bit dicriminating message annoying Chinese and Korean , but I asked the host to fix it. I guess it is his simple error but if you still find the message making you feel like a burglar, please remind the host.
Please enjoy the calm in the center of Roppongi with all these greens and shops. This location is fabulous.
