We used this place for our family friend reunion.
Pro: walkable distance from train station. Has rental bicycles for local transportation (i.e to convenient stores, good local bakeries etc).
The house is equipped with games and Amazon TV which helped entertain the kids.
The host accommodated us with sets of futons for the traditional room despite being last min request. It worked out fantastic with young children.
Bedding was VERY comfortable and they provide IMABARI towels (super fancy!)
Con: the house is rather old so your feet can get pretty cold. Make sure to wear socks in the winter.
I feel I got a lot of communication from the host which ended up burying the info on how to get into the house, as this information was imbedded in the middle of one of the emails… we struggled to locate the info when we got to the house. Maybe a single email with a title of “How to get into the house”would have been helpful, rather than having that info imbedded in a very long sets of information.
