We should have stayed longer, period.
First of all the location, at least for me is perfect. Wiesen is a bit off the main path, so there are not thart many tourists there, but the scenery is still gorgeous, and you get in my opinion a more intimate experience. The hotel has been very tastefully modernized, the rooms are excellent, first class large shower, very comfortable bed, dinner and breakfast served on a gorgeous terrace. It would be very hard to complain about this hotel. Excellent throughout, highly recommended.
The hotel also has a gin collection, there were more than 50 gins and I believe 15 tonics, so ordering a gin tonic is a bit more involved then usual. although I am not a gin fan myself, I found it a very nice touch, and different from countless other hotels.
Wiesen is part of Parc Ela, a large natural park in Switzerland that offers many kms of hiking trails, and the famous Albula railway is very close by, the hotel is an excellent base to start trips into the countryside.
