I would definitely recommend the ninja house for a completely unique experience - although as the ad states it would not be suitable for children or older people as there is a lot of climbing involved!! It is very spacious compared to other Airbnb properties we have stayed at in Japan, and the roof terrace was such a bonus. Shin was a very attentive host and was extremely helpful in providing tips and information both before and during our stay. The checkin process was absolutely seamless thanks to Shin's instructions. Great fun in a good neighbourhood! Thanks again Shin!
