Go ahead, treat yourself. If you're coming to Franz Josef to hike a glacier and/or a thousand other gorgeous trails, you're eventually gonna be sore and sleepy. Why not show yourself a little love and stay in the swankiest treehouse, complete with heated bathroom floors, huge amazing shower, giant comfy bed, complimentary wine, and delicious breakfast baskets with tiny muffins...MUFFINS! We've never felt so fancy.
Also it's such an easily walkable town, so location is perfect, and their on-site restaurant is delicious with friendly, fast service and great drinks. Stayed for 2 nights and miss it already.
