Traveller reviews

“It was lovely to stay- Helena was fabulous & would highly recommend if you are staying in Interlaken”
29 Aug 2025
Helena was excellent; very professional, polite and welcoming (very rare in Switzerland to find all those traits). Property was very close to the train station, breakfast was good and the room size was good as well. There was plenty of space to sit in the garden & enjoy the view to the snowy mountains. Will definitely recommend a stay.

“Well located, clean accommodation run by friendly helpful staff .”

“Perfect stay”
31 Jul 2025
Traditional Swiss house in a beautiful location with easy access to the train train station, shops and restaurants on foot. Comfortable room with an amazing view. Basic but good breakfast. Helpful information about the area provided at the Guesthouse and lovely staff on site. I would return to this accommodation

“Excellent - keep doing what you do - you've got a great guesthouse there.”
