We stayed 2 nights at the end of our trip in Japan. The studio is good for a couple 2 people Max.
Check in is easy as the owner lives and works next door. They also have pocket wifi very useful. There is a metro and a JR station close by. 10 min walk. The neighborhood is not the most touristy but has all you need a mall and convenient store just a few steps away. The host also left some cookies and tea for us that we appreciated for breakfast
