I stayed at the Padulella for a week at the end of September. Air con was not an issue as the temperature by day did not exceed 30 degrees. I did have a similar experience to other reviewers in that the bathroom/shower was in dire need of a substantial face lift. (The shower door would not stay on its tracks. Cracked tiles in need of repair etc.) I also found the bedroom sadly lacking in storage space. One drawer in the bottom of the wardrobe for two people for a week. Our room was on the road side and, while sitting on our balcony in the late afternoon was quite pleasant, it could get noisy. I was woken up by traffic (motor bike) twice in the week.
On the plus side I could not fault the attitude of either the staff or the owner. They couldn't have been more helpful.
Drinks were reasonably priced.
The breakfasts were German/continental - ham, cheese, coffee -with some Brit additions, e g cornflakes/cereal, tea. Not terribly inspiring with the exception of the croissants which were excellent. Dinner was a different matter. As part of a large group, I didn't know how hard a deal the tour operator had driven with the hotel management and therefore cannot comment generally. I will say the the food lacked imagination,and there was a marked shortage of fresh veg., but on occasion the chef really surprised us with delicious soup and a fish dish.
On the question of location, I knew before I booked there was a ten minute uphill walk between the hotel on the town, so it wasn't a problem, except that you do need a torch to warn drivers of your presence after dark. The hotel's elevated position does afford some lovely views.
