This was my second time in Naples, but what really made this trip special was not only Sal's amazing and cozy apartment, but also the degree of care he took of us. You cannot imagine the information, local favorites, and tips for sightseeing/dining/having a great time that he gave us from the very start. He was also so attentive and always responded within minutes of not directly to our messages, always answering our questions and advising us on what to do if we ever needed it! Because of Sal, we got to experience the best times in Naples, dine at the greatest restaurants, and enjoy the Neapolitan area without worrying about were to go/how to look for local favorites.
Sal's apartment is very well placed in the Spanish quarter, and gave us direct access to the bustling via Pignasecca, where we basically had almost all our seafood experiences.
It is five minutes away from the Toledo metro station, which is a couple of stops away from the Garibaldi train station (that's where you take the Circumvesuviana line to go to Pompeii and Herculaneum)
It's a short walk up to the Naples National Archaeological Museum (I think it takes 10-15 minutes but we kept stopping every few steps to admire the streets and architecture)
It's around ten-15 minutes walk to the Castel Nuovo and Umberto Gallery, and so is close to the coastline as well.
TIP for a great and cheap breakfast: go to the charcuterie/cheesemonger facing the entrance (but first get some bread from the baker right next to it). Ask the owner for a prosciutto and fresh mozzarella sandwich, dash of olive oil, and some pepper. We had this every day!
Really very well connected.
Finally, Sal's mom was a great help during our stay. She lives adjacent to the apartment and was very kind enough to keep our luggage before check-in and after check-out, so we never experienced any difficulty with that.
Highly recommended, and can't wait to go to Naples again and stay there!
