We (2) spent 4 nights in Napoli. Lucio was easy to communicate with during our stay and he checked in on us daily. Check-in was no problem and Lucio provided detailed instructions on how to get from Metro stop Toledo to his apartment.
The place is nice and clean. It's 3 min walk to Metro stop and the famous Via Toledo. Good restaurants, gelateria, and bakery all nearby. Interesting to stay for a few days in the Spanish Quarter. Would definitely recommend.
And Neapolitan pizza is awesome.
