I had a really lovely week at Mario's place. I didn't see Mario, but was let into the apartment and shown around by Ulla who was a wonderful host. She showed me the apartment and gave me lots of fabulous suggestions and connections. The apartment is quiet, even though it's only one block behind the crazy main street down into town. It's cool, too, but has a large wonderful rooftop terrace if you want to sit outside. Inside the apartment was spotlessly clean and tidy, and would be very comfortable for a family, couple, or single traveler. It's ideally situated about 2km from the very centre of town walking down one of the main strets. A lot of the great sites are walkable. There are local tube stops very close by, as well as tons of food outlets, trattoria, pharmacies and other amenities. I got a great taste of Napoli's chaotic, noisy, busy, beautiful, dirty, vibrant life and loved every minute of it. I would heartily recommend Mario's place to any traveler wanting a great slice of Neapolitan life.
