Casa Berno is a beautiful hotel on the side of the mountain with great lake views. The hotel is very clean and well appointed. The staff does a great job of service, but their English is limited. Food was very good and well presented and prepared, even if a bit expensive for dinner. If you are driving, getting to the hotel on a narrow two way road that is only capable of one car getting through in many places is a bit of a challenge and parking is tight. We were there in mid June and it was in the mid 80 degrees Fahrenheit. That made if very warm sleeping without air conditioning. They did have electric fans available which made it bearable. Getting down to Ascona only take a short time and it, and the surrounding towns and valleys, is a wonderful place to visit.
