Foremost we appreciate the cleanliness and comfort of Graziano & Jackie's flat. It was nice coming back to after a long day out. As others have stated, the location is immediately adjacent to the bus stop, so transport (especially with the local app) is a breeze.
The rating reflects (1) the parking, and (2) host communication. While it's true that parking is free, there is no designated space for the AirBnB, thus parking was difficult and, at worse, we waited for 42 minutes one evening. Communication was difficult at best; messaged frequently regarding delayed flight, but late response there after neglected to acknowledge my notification attempts. Upon arrival, Marco - the greeter who opened the flat to us - appeared to have no knowledge of our delay and of course was unhappy considering he had an early work shift the following morning which we absolutely empathsize with. Ultimately, he was courteous and so patient with us.
If you don't have a car this is a great value and location is excellent.
