I am falling short of words to describe how wonderful the place is. Christoph and his wife are very helpful, warm and absolutely wonderful couple. They gave us so much information about planning our day excursions in Interlaken. They even gave us a pair of sun glasses for our baby since we did not bring one. They serve hot breakfast with tea/coffee. The view from the room is breathtaking and you just cannot get enough of it. The bed is large and comfortable, bathroom is spick-and-span.
In short, they make you feel special and help you make the most out of your vacation. The place is a short bus ride away from Interlaken West and Christoph gives a bus travel pass to make all your bus rides free.
We have stayed with a lot of wonderful Airbnb hosts and I have no qualms in saying that Christoph's place has been my best experience so far, both in terms of comfortable stay and value for money. I recommend his place 1000%.
