We loved the couple of days we spent in Naples, at the appartement in Vomero. This is a very nice neighbourhood, with lots of restaurants and bars. You can walk to the city center (about 30 min) with spectacular views over the city and Mt. Vesuvius, or take the funicular, which is a few steps away. Valentina is the perfect host, helped us with tips for restaurants and so on.
Definitely recommend the place!
