Salvatore&Marianna were really great hosts, very helpful and fast at answering all our questions. They even called us a taxi for our departure, which we are very grateful for. The apartment is super clean and very well equipped, located right in the middle of the historic centre with many bakeries and shops nearby. You can reach the underground in about 10 minutes by walk and you are close to all important sights. The only thing you need to get used to is that Naples is a loud city, even at night. So you might actually think of bringing earplugs with you...
Overall, Salvatore&Marianna made our stay very enjoyable and we would highly recommend their apartment.
