Stayed a week with 4 adults and 2 kids. The house had a great location, with a short walk to the nearest subway station. Getting there from Narita station was no problem, since the host gave great instructions on how to get there. The host also met us at the station, and walked with us to the house, and check in.
The house was nice and clean. Was great with 2 toilets, since we were 6 persons. An other great feature was kitchen had place for 6 persons. Close to street with nice pubs and restaurants. Grocery shops were also close.
All in all a great stay, both house and host.
Can really recommend this for others.
