We were very comfortable to stay in Koichi's apartment. It is really cozy as described, has everything we need that including washing machine, microwave, WiFi, TV. It is also quiet and convenient. Supermarket and convenient store are just 2~3mins by walk. Koichi is a very good host and easy to communicate.
He prepares hot drink and tea packs in the room. He is thoughtful to pick us up to station when we leave.
This is a good experience to use Airbnb in my first time. And we will recommend our friends to visit your apartment and hope to see you again.
