Carmelo was very nice and very helpful, giving us advice about what to see, and he left us fruits from his garden as well as water. (More fruit than we could have eaten actually!) When there was a problem with the wifi, he fixed it immediately and was very nice about it.
The flat is very well situated, right near bars, restaurants and shops, but a bit away from the main roads so calm.
All in all we were very pleased and would definitely recommend Carmelo's flat :)
