Wonderful location! Spotless!
We were a little bit surprised that there were not 3 bedrooms, but it totally worked. Downstairs as you walk in there is a bedroom with a large closet, a full bathroom with a washing machine. Upstairs is the kitchen with a table, then beyond the table is space to lay out your sleeping mats and another upstairs toilet room. The space worked great for us because why hang out inside when you are in TOKYO?! A tiny suggestion would be to pull the hanging lights up closer to the ceiling - dorky us bumping our heads on the regular.
As far as location - it was perfect for us - super convenient for exploring, easy to get to the station, quiet, great shops and restaurants nearby. Rika was an amazing host - we would 100% choose her place again!
