If you are looking for a room for 3 or 2 people in Tokyo, then I'd recommend this place for you.
Even though the room is small, It is still a pretty good room for rooms in Tokyo
The place might be a bit far from the tourist spots but, the place is only 3 minutes away from the station, so no problem
Although I'd recommend you to bring your own portable wi-fi as the wi-fi is intended by the owner only to be used for maps and messages
