Big comfortable room with a/c. Francesco was nice and friendly.
It is the perfect location to discover Naples. It's close to Garibaldi station and it is steps away from the Decumani/centro storico. Grocery stores and all commodities just outside of the building. It's walking distance from everything you'll want to see, even Castel dell'Ovo and the Catacombs although they may seem far on the map.
Regarding the safety....well Naples looks weird in general. That's what makes this city so special. I'm a female travelling alone and I can tell you it is perfectly safe, no worries!
