A really nice place for a big group. You can easily fit six adult in the house. The kitchen is really nice and big enough for everyone to dine together.
The room on first floor has a bed for one person. The other five would have to sleep up stairs on futon on tatami, which is quite nice and added Japanese local experience. There is a small balcony on the second floor. The window facing the front of the house is huge!
The place itself is a little far away from the station. If you have big luggages, better take a taxi. Taxi ride from Asakusa station will cost between 500 - 800 Yen. You can take a bus which as well.
Walking from Asakusa to the place is quite nice if you enjoy walking. It will take about 15 minutes to get there from Asakusa station. Recommend to walk along Sumida river, day or night to enjoy the view of Skytree and the sea breeze from the river.
There is also a rental bicycle station nearby at 7-11 but I didn't get a chance to use them.
