We stayed in Borgo San Benedetto in June 2015, the hotel is located in beautiful countryside surroundings and the gardens/grounds of the hotel itself are maintained to the highest of standards. The room that we stayed in was part of a block of four, it was bright and airy and beautifully decorated and we didn't hear anything from the neighboring rooms. We had our own personal patio area with two loungers and a table and chairs and looked onto the gardens.
Our breakfast was included in our stay and was served in the main building, breakfast consisted of a selection of cold meats, cakes, yogurts and pastries. There are two pools separate pools and we never had a problem finding a lounger.
The restaurant at the hotel is Michelin listed and I would definitely recommend eating there but not on a Friday or Saturday night as it was so busy in there, the week nights seemed much more relaxed, however despite being busy the food was still great.
The only downside I found to Borgo San Benedetto is that there didn't seem to be anywhere at the hotel to have a drink in the afternoon when the sun was a bit hot and there was not a fridge in the room to keep anything cold.
Overalll, we had a fantastic time at Borgo San Benedetto, the staff were very friendly and would definitely visit again. However, if you do plan to visit I would definitely recommend hiring a car as there isn't much to do in walking distance, but plenty to do in a short drive.
