Everything was fantastic! Kei is a great host, he took good care for us and we felt at home there. Next to the room there is also a shared living- kitchen space that we could use- that was really handy! The house seems to be a bit far from the touristic locations, but it is well connected with train and metro, therefore you can get anywhere you want quite quick. It is also very handy that it is possible to get from and to airport in one go, without changing the trains, but keep in mind that Japanese rail pas don't work on that line and you need to buy a separate ticket. Thank you Kei! See you soon!
