My friends and I stayed at Olimpia and Rosario's place for two nights and had a great time! They were very helpful with anything we needed, be it calling a taxi or lending us an adaptor so we could charge our phones. They were so accommodating when we had a late night out in Piazza Bellini and woke them up to open the gate for us. The location of the apartment is close to good restaurants and bars. We would recommend a stay here when in Naples.
