You get your own tiny apartment! It has everything including the kitchen sink. It is only missing the rice cooker. :-O Seriously, how can you survive in Japan without a rice cooker. lol
A few days before checking in, he sends you a message with the address in English and Japanese. The Japanese is useful for the taxi driver.
The email from AirBnB as the wrong location.
When you check in, he shows you around and how everything works. There is a lot of information already printed and hanging up in the apartment.
He is always available through text messaging and responds right away.
So his written English is good. He is a little shy on the spoken English.
