Delfina should be a superhost!
The room is comfortable- there is everything needed to live: comfortable bed, private bathroom, air conditioning. Fully equiped common kitchen. The only minus is that there is no lift in the building but this is not up to the host.
Apartment is located near the main street (but the neighborhood is quiet) and it takes about 10-15 mins by walk to get the 'city center' with full of little restaurants, cafeterias, shops, metro station.
I really enjoyed time spend in Napoli.
