I spent my holidays at Casale Granati with 9 friends for one week. All in all it was a nice week and we felt comfortable at the house. There ist plenty of space for 10 people, every room with its own bathroom. The rooms are a bit old and musty, most of them have no windows, but we didnt spent much time in them anyway so it was ok. The Highlight of Granati is definetly the pool and the chill area in front of it. The Padel Tennis area is also very nice, there are 4 rackets as well as some balls. The whole area is private.
But there were also a couple of things that didn't go so smoothly. The communication between Novasol was tedious, they aren't really helpfull or could answer the questions because its an agency wich just organizes the airbnb rental. The Keyholder/Owner doesnt speak english, luckily we had someone who spoke Italian...
In the end there are coming a bit of extra costs, you have to pay 200€ in cash for cleaning, 50€ for the trash removal and the energy cost for your stay (in our case it was very low, so he didn't charge us wich was nice) and you have to pay 100€ deposit in the beginning.
Worth to mention is that there are at least 2 Foxes nearby. We saw them almost every night, they are not really aggressive but in the first night we didnt know about them and let some shoes in front of the doors. The Foxes took them and we never got them back...Would have been nice if the owner said something to warn us.
