Hello everyone,
Valentina is great host and has great appartment close to everything you need in Naples (historic city center, underground, train station, port, night life, shops etc. - everything we could think of it was close or reachable via underground for 1,2 euro per ride). :-)
Valentina gave us great tips at our arrival where to go and what to see and left us map with her own marks what's best to see in her opinion.
In nights street was loud but it is everywhere in Naples so i really cannot think of anything that was bad on this accomodation.
Recomendation to everyone who goes to Naples! : )
