I am flabergasted to read the review prior to mine, but all I can say is "to each his own". My opinion of this hotel couldn't be more opposed to the one previous.
We were just blown away at how lovely this hotel was. It is charming and you feel like your living a fairy tale. The views from the rooms (which were very comfortable and clean) was out of this world. The staff were friendly and helpful. The breakfast was very nice and included the usual Italian fare - cakes, yogurt, breads, cappuccino etc.
If I ever get back to Sorano the Hotel della Fortezza would be my #1 choice of accommodation, however if you are the type of person who can't walk 3 minutes to your car, you should probably miss out on this unique gem and take yourself to the nearest Motel 6.
