We stayed a week end in Napoli in Luca's appartment. It is very well located just near the old town. Everything can be reached by foot, otherwise you have the metro nearby.
The appartment is spacious, cosy and very well decorated. We loved it!
We were welcomed by Luca himself who gave us very good tips on what to do around and indications on best places to eat.
I fully recommend this appartment :)
