Kotaro's place is a wonderful spacious apartment that is above his business.
One thing that sets this room apart from all other rooms is the heating. This place is well insulated, and must have heated floors. Having lived in Japan for some time, I can state with confidence that the floors are usually cold in the morning. Not once did we have to use the air con.
Kotaro is a very friendly man, and I only wish that I could have stayed a few more nights here!
