This guest house is more than perfect! I will definitely stay in here again if I come back to Tokyo. The building is newly built and clean, and the room is fully equipped with all the things you need. It even has the laundry machine. Also, the bed was very cozy.
I could easily get to Tsukiji market which is only 5 minutes far from the house, and avoided the long queue. Also, Ginza is in walking distance. Highly recommended!!!
