This is an elegant, period building, the rooms are large and spacious. We had room 308 on the front of the hotel which gave us a balcony with a Mountain View. Because it is an old building, it does not have aircon. It was hot while we were there, but we were able to sleep with the windows open and the fan on; there is a road at the front of the hotel, but iit is very quiet and nothing happens after 10.30! We had B@B but lunch and evening meals are available. The breakfast buffet is excellent - including sparkling wine!The hotel staff are very helpful and everyone speaks excellent English.
The housekeeping is excellent. We stayed for 7 nights; the sheets and robes were changed three times while we were there. The mini-bar contents are included in the cost and are replenished every day - I enjoyed the half bottle of Prosecco every evening after a day in the mountains.
The hotel is 5 minutes walking from Interlaken Ost train station and boat station so getting around is very easy. I would recommend getting the Swiss Trail Pass as it gives free travel on trains, boats and buses, and discounts on some of the mountain routes.
