Fira's apartment was a great place for our trip to Napoli and its surroundings. The location is amazing, very close to the port that ferries depart from, next to a metro station, and walking distance from many of Naples' top attractions and restaurants.
The apartment is indeed rather small but has everything that you need for a couple of nights and its location is perfect.
Fira was a very helpful and communicative host as well, 100% recommended :)
