The appartment is very nice and clean. All is brand new inside. Special mention to the two bathrooms with italian showers (pretty convenient when you need to rush in the mornings). Location is excellent; 5 minutes walk from the old quarters, 10 mn walk to Garibaldi train station (to go to Pompeii and Erculanum) and 10 mn walk to the ferry peer (to go to Procida). Duomo metro station is just below your windows.
Erika is very nice and can arrange transferts and breakfast in the room for you. She even organized a late arrival for us as we landed in Naples at 10 at night.
We definitely recommend it.
