The Ninja House was perfect for our stay. We were three adults total and found the size to be just what we needed - cozy but enough room to comfortably live and sleep. It was a unique space that was fun to climb. Felt like sleeping in a tree house loft to me.
Shin provided everything we needed for our stay, provided amazing communication including walking directions to the house from the train and a ton of recommendations in and outside of Tokyo as we also spent time in other cities during our trip. Because of an unplanned emergency we had to delay our check-in by a day and Shin was very accommodating.
We loved the location as it was convenient to all the sites by subway, while having a ton of dining options in the neighborhood itself. We can't wait to stay again!
