My parter and I stayed at Elisabetta's apartment for 3 nights and really enjoyed our stay. The apartment was in great location close to a good supermarket and surrounded by fantastic landmarks, shops, cafe's, bars and restaurants.
The apartment was very clean, homely and nicely decorated. There was good air conditioning and good and fast wifi.
Elisabetta was unable to meet us but arranged for a neighbour to let us in on arrival at the apartment and Elisabetta was very friendly and offered to assist if there was anything we needed.
The only very very minor negative would be that there was a band playing quite late on of the nights at a bar just out the front of the apartment but every other nigh was very nice and quiet and this wouldn't deter us from staying here again.
Overall we had a fantastic stay and would highly recommend staying at Elisabetta's apartment whilst visiting Naples.
