It's really at top of the world. The cottage is at the top of Nessalu mountain top. Excellent if you want to spend time in nature.
It's difficult to find so contact the owner before you go there. Owner is very friendly and very helpful. She knows only German, but she was really nice to use Google translate to talk. I want to really thank her for that.
I think it's good for a group 10-15 people. But it will be amazing for a couple too.
