Wow, I've been to Japan almost 10 times, and Kai's place is definitely the best Airbnb I have ever stayed in. I traveled here with my mom, dad, brother, and boyfriend. We booked the Airbnb 6 months in advance since we came during a busy time.
The amount of space that is in this home is incredible. The location is so close to everything in Tokyo (walking distance to AMAZING restaurants and a main train station). It is honestly impossible to find this amount of space in such a central area.
The amenities that are here are incredible as well. There is the usual soap, shampoo, towels, hairdryer, etc... but Kai and his wife also provides feminine health products like pantiliners and high quality hair gel and spray. There is a hot water heater for you to make tea.
On Christmas Day, Kai's wife dropped off some of the best pastries I've ever had and a bottle of wine. When my mom couldn't figure out how to use the washing machine, Kai's wife came over and visited us in person!!!!!
Kai and his wife speak amazing English, but if you are Chinese, I recommend this Airbnb as well since Kai's wife speaks fluent Japanese AND Chinese! My mom was so happy to have met Kai's wife. These are real people in Japan and they were so helpful. I loved this Airbnb.
