We stayed at Schönbühl with the Expat Explore Europe Escape Tour and this was certainly one of the best hotels we stayed in, bearing in mind that all hotels/hostels were either 2 or 3 star.
Our Coach driver perfectly manoeuvred the bus all the way to the top where the hotel is located on the edge of the mountain, which pretty much gives all rooms a lovely view of the valley. We stayed in a twin room with very colourful bed linen (probably ideal for teenagers travelling!), however the room was extremely spacious and we had an excellent view on th top floor.
The food on both nights was excellent, however only the first night's meal was included. As the owner offered a typical swiss cheese fondue on the 2nd night for a reasonable CHF15, we opted for that and it was a wise choice, as Switzerland is extremely expensive, especially if you chose to dine out.
The bathroom however was tiny and it is very hard not to spill water all over the bathroom floor, with the existing shower curtains.
We were given a complimentary day pass to travel into Interlaken either by Bus (10min from the hotel) or by train (15 min). Both options are great and you can fill up your water bottle along the way from one of the many waterfountains, which offer clean water.
All in all it was a good stay and I surely would love to come back in Winter, as this must be a snow paradise!
