That place was very convenient in terms of location. There are two Oedo-line stations within 7-8 minutes walk. I felt that Kachi-doki was nearer when you don't grab a quick breakfast at a famous fish market in Tsukiji side.
Facilities are all new and made in Japan including washlet. You will enjoy those equipment when you use it because those are new, beautiful.
Rooms are small but since I was on a business trip, I did not much care about it. I was always out during day time. Even if you are tourists to Japan, it will not be a problem. You will be busy visiting many place day and night, and you don't spent much time in the room!
They don't have a lift. I had to work hard when I climbed up to second floor with my 20-KG suitcase.
The host is very attending, generous to offer anything you need. She provide cleaning service once every three or four days when you stay there longer.
I will be back to the place on my next trip to Japan for sure.
