"Very large, clean room. Wonderful balcony overlooking a river and ruined medieval fortress. Large bathroom. Difficult on-street parking on a steep road (drag your bags into the hotel). No refrigerator or microwave, but very comfortable and well air-conditioned. Very friend staff. Affordably priced. In a cute little town and well-located. Would happily do it again."
