I had a really enjoyable time at Marcello's apartment in Naples. It is in the historic centre and is just a 6min walk from the metro station. I was travelling on my own but felt very safe walking around the area in the evening. The apartment was down a narrow alleyway but I felt safe - many of the neighbours sit outside on the street in the evening so it was not deserted. You have to walk up 5 flights of stairs but it is worth it as there are 3 terraces giving views of the city and Mt Vesuvius. Check in was easy - I met Marcello's mother at the apartment. Amenities were good - the kitchen was well stocked, the wifi good, the bed comfortable and there were a number of useful local guidebooks to look at. A very good apartment to stay in if you visit Naples.
