Salvatore is a great host, a person who is always willing, easy to communicate with and flexible.
The flat is just as it looks in the pictures. It is a very nice flat and is equipped with all the basic comforts. The location is exceptional, close to many of the sights in Napoli and close to good restaurants and pizzerias.
If I return to Napoli I would come back to Salvatore's flat. 100% recommendable.
