We were very happy with the apartment, it was neat and tidy, and close to the public bus, from which we were able to explore Naples!
The apartment is in a fairly safe area of Naples, with grocery stores nearby which are open for a long time, giving us plenty of time to get everything we needed. The host did not speak English, but was very gracious in communicating via Google Translate, and managed to communicate everything that was needed. The apartment itself was very nice and clean, the layout is good and has a modern kitchen, and it is gated off from the street, so it's a little hard to find, but is very nice for safety. My only real comment is on the street, it's a somewhat tight and had a lot of traffic during the evening rush hour, making it very difficult to walk down at that time. At other times it was pretty empty though.
Overall, 5 stars, would stay again :)
