Koichi is a very helpful and considerate host. Due to traffic congestion on the highway, we arrived an hour later than originally schedule. Koichi communicated with us through WeChat and waited for us in front of the apartment. He escorted us to the flat and showed us the usage of the electric appliances.
On the day we left Tokyo, Koichi kindly offered to help us keep our luggages in his car and delivered it to Shinjuku station where we took the airport train.
