Davide's place is very well located. Me and my girlfriend could reach all places in Naples in very short time.
Communication with him was easy, thus making the check-in and out process very smooth. He also helped us with the transportation to the airport.
If you go to Naples (and of course, stay at his place :D), I recommend you to check Davide's blog about the city and his restaurant recommendation. We tried some of them and the experience was amazing.
