Mr. Kazuhiro and his three cats is a lovely family. Mr. Kazuhiro is super warm, friendly, and generous. He is always there to help and give you useful advice. He was kind enough to spend extra time and effort to make sukiyaki at midnight the day before I left, because I told him I really wanted to try wagyu beef.
The space is very big compared to previous Airbnbs I've booked in Japan. The room is warm and cozy. Mr. Kazuhiro has prepared everything you might need, from deodorant to hair blower. The showering space is surprisingly big. Traffic is convenient: the house is very close to Yutenji station, where you can get to Shinjuku and Ginza directly. There's a very affordable supermarket near the house that closes at 1am. Although the house is right under the railway, it's surprisingly quiet at night. Kazuhiro's cats are cute and friendly. There's nothing you can complain about. You really can't regret staying at Mr. Kazuhiro' house.
