Kei is extremely helpful and accommodating. You could not asked for a better host. The station is 6-7 mins easy walk to his apartment which is situated in AETO station - direct train from Narita airport. It is easy to take the train to the city and see the touristy spots.
He treat us with warm hospitality so I would really like to thank him sincerely for being a good host. The house was clean and quiet there is a good supermarket in the mrt station. There is a positive feel that you feel like a family and we really enjoyed conversing with him.
Although we didn't stay long enough to need it. Besides Kei's obvious enjoyment in hosting people, the home is a great chance to see Japanese people's lives. Kei is definitely a star host. Great choice if you are visiting Tokyo.
