Salvatore has a very nice place on the top floor of an apartment complex in the Spanish quarter (no elevator so you will need to carry your bags to the top). It was large enough to comfortably fit a group of six with a fully functional kitchen and a beatiful view of mout vesuvius from the balcony.
Salvatore was very responsive allowing for easy checkin and provided insights into where to eat in the area. Great host overall!
Disclaimer:
The area is a little rough, although as two female traveller's we didn't experience any trouble, there were a few interesting characters that would watch us as we went to and from the apartment. Would recommended for groups and not solo traveller's.
