Francesco was incredibly accommodating and had a wonderful apartment. He arranged for us to be picked up from the airport, taken to Pompeii & Vesuvius, and made a reservation at a restaurant on our behalf was all around incredibly useful.
The apartment was clean and well laid out, the upstairs bedroom has full A/C and the downstairs shares a portable A/C both of which helped tremendously in the 35-degree heat. There was even an umbrella by the door which saved us during a sudden thunderstorm.
In summary, Francesco was very generous with his time, helped us a lot and kept a lovely apartment only a 5-10 minute walk from the centre (though it is down a big hill).
