I spent 10 days at Carmine's great place. I can only recommend it. The huge terrace is splendid, offering an amazing view on the city and gulf of Napoli, Vezuvio, port...
It's a good location too, while in the center, giving you the calm retreat feeling you might need after a busy day in Napoli.
Carmine is a perfect host, caring for his guests and relax. He knows the city well, so he can tell you all you need to know.
Next time i'm staying there, it's sure!
