We had a lovely stay in this appartment. It is very comfortable and clean and the location is superb. The communication was very fast and they were very helpful. Be aware that if you want to drop of your luggage at the appartment using your own car you are entering a ZTL and pedestrian zone which can give you huge fine if your license plate is not communicated to the authorities by a local garage/hotel/air BnB. So check al the parking options and your luggage drop off carefully before entering the ZTL zone as there are camera's that scan your license plate.
We would definitely stay here again though!
