The sauna! The house was clean and very well maintained, down to every detail, and also practical, with sufficient hanging options for towels and a place for wet shoes. The location is beautiful, with a view of trees and snow.
The bed was quite soft and slid off the wall when you sat up. The sofa was not really comfortable, nor were the stools at the dining table, so sitting comfortably was only possible in the armchair. We really missed that.
