I have been to Naro many times visiting family. I have often stayed at an agriturismo but decided to stay in the center of Naro for a few days for the convenience of being able to walk to the town square and Via Umberto. Naro is an old town with many very old structures, some of which are in disrepair.
I chose Francesca and Pino's place as it looked like the apartment was new. It was in fact perfect! All the tiling and lighting is new and there is clearly new plumbing and electricity. The place was super clean.
Francesca and Pino were very friendly. It was nice to chat with them. They only spoke Italian. Pino was quick to use a voice translator if my Italian failed me.
They have a few business cards with recommendations of places to eat or visit. These are the places the locals go so follow the recommendations! If you are only able to speak English, I recommend Bar Social on Via Umberto. One of the guys who works there is fluent.
