We stayed at Simones only for one night, but we still enjoyed it. The view from the balcony is stunning, the bathroom is clean and we even found the air conditioner, which was so helpful in the heat.
The kitchen was rather basic but it didn't bother us. If you come with the car, you better check out your navigation, as we initially passed the right turn from the highway and had to cross the city from another end (which is not that far away anyway).
Overall: Temple of the Valley is so worth visiting, especially in the evening hours (in August and September it is open until 23 o'clock), and the garten inside, "Giardino della Columbetra", is a true paradise.
