We stayed in the apartment for 4 days. It's very clean, stylish and well equipped (hairdryer, all the kitchen utensils, iron, laundry machine). The apartment is perfectly situated in the historical centre of Naples (moreover it's 15 minutes slow walk for the Garibaldi Station, less than 10 minutes for pizzeria Da Michele).
If I'll be planning my next trip to Naples I would definitely choose to stay at Anna's :)
