Tiziana's flat is super big ! It was clean, we had shampoo & shower gel. Tiziana's was super flexible on the arrival time. You will find everything in the flat (iron, washing machine, big kitchen). It is near a metro station that will bring you almost everywehre in Napoli (and to Pompei & Vesuvio) and most of the areas are also reachable by walking if you're fit.
It was a great experience and would recommend it !
You have to know that the flat has 2 rooms that give on the street that is quite lively, so you will hear sounds from the street in the morning. 2 others rooms are calm. Globally the area is lively and I suppose not the richest area, but we felt safe (but we were 4 guys).
