I recommend Raum Sanso 100%. Everything in my stay was perfect. The house is very nice, clean and cosy - located just 10 mins by foot away from 2 beautiful lakes. The hosts are extremely kind and did everything to make my stay great. The breakfasts and diners were some of the best food I have enjoyed in Japan! Hope to come back soon
