We stayed 3 nights in Fabrizio's appartment, and we felt like home.
First of all, the ubication is really nice with only 5-7min on foot you are at the most centric streets of Napoli and the metro station of Dante is in front of the appartment.
Secondly, the appartment has 2 private rooms with a sharing living room. Each private room has a double bedroom with air conditioning and a private bathroom.
If I came back to Napoli, surely I would return to Fabrizio's appartment.
