This is very nice and clean place for one person. It is close to Tsukiji station by walking distance. I used google map to show the direction from Tsukiji station to find the place which is very easy. The Tsukiji fish mark is just opposite to the street, and easy for you to go to watch tuna auction in the early morning. There is a market street just besides the fish market, where you can enjoy most fresh sushi and sashimi. There are convenient store, sushi store etc close by.
The room is ver clean. Wifi speed is fast, the host's response is quick as well.
This is definitely a good choice for me to stay here again when I travel alone to Tokyo next time.
