We stayed there to see Kakunodate's cherry blossoms, and the location is not only amazing, the house itself was also comfortable and welcoming. I was able to bring my 4 year old along and the dogs were very well behaved and gentle. The amenities and facilities were great. They do not provide dinner so you can eat nearby. The breakfast provided was amazing. It was quite cold still in the end of April, but the room was equipped with heaters so that wasn't an issue. There are other guests as well but everyone was quiet so that's no issue. To make a booking with kids, we initially just put down 2 adults, then e-mailed the owners right after we received the confirmation to add 2 kids. You can pay in cash and the price of kids staying is less than per adult. It was a really excellent experience, we will be returning in autumn again.
