Great location and responsive hosts. The two comments that we would make is a) the kitchen lacked a few essentials such as a cutting board, paper towels, etc. b) there were no views from the apartment and the windows were all frosted for privacy.
We opted to have bedding for 6 (although we were only 4 of us) since the double beds were a bit small for us and we wanted to spread out. There was a small additional charge for the extra bedding.
For the cost, the value was good, as it was one of the most reasonable places we could find in Tokyo during Sakura season.
