I will start out by saying this is not the fanciest hostel I've ever stayed at. Don't expect anything beyond basic. Balmer's is my favorite hostel because it is so fun. There are many young people staying there, the metro club is great, and the staff is quite helpful about booking excursions. My three days at Balmer's are among the best times of my life. If you go to Interlaken, do yourself a favor and stay there!
