The apartment is very well equipped, spacious and comfortable. We had a lot of helpful advice from the host as well, mostly around things to do in the area. We went with a family of 4 and there was more than enough space for everyone.
Even though Thierrens itself is a small place, it is very easy to get to a lot of locations you would usually visit, like Bern, Geneva, Lausanne, Gruyère and so on. Totally recommended both if you want an active holiday or a chill out one.
