For the first day of the arrival the Air conditioner of the room I was staying in wasn't working and have been cleaned form many many months.
No matter how many times I tried to inform the host, she wasn't doing anything to fix it. The temperature of the room and the outside temperature have 3⁰C different.
In order to protect my health I was forced to move out and stay at a hotel in 00:00, because Mrs. Tanaka didn't inform me until I call her at 23:10 and she told just sorry.
The bathtub was really small for one person.
SHE WAS THE WORST HOST I HAVE EVER STAY
