I stayed at La Castellina for 3 months and loved every moment. The location was perfect for me. It was only a 5 minute walk to Line 1 and Line 2, allowing me to travel anywhere I wanted to go. The ferries to Capri, Procida and Ischia can be reached within a few minute train ride or a beautiful walk. There is a fruit stand right around the corner and a full market just down the street. The space is quiet and the bed was very comfortable. I slept very well. The apartment is well equipped and has everything you need. The host was very responsive and super nice. Just a quick note that you may want to take a taxi to the apartment when you arrive, as walking with luggage to the location is not easy. The streets are not meant for rolling suitcases,. The place was perfect for me, but if you are a large person, the shower may be a bit small. I loved La Castellina and highly recommend it. It truly felt like my home for the 3 months I was there and I will stay there again the next time I am in Napoli.
