We were 3 couples enjoying life in Napoli. We had a great stay and we were very happy with the apartment. It was perfect for us as all the rooms were very big and nice with everything needed.
In google maps the neighbourhood seems shady, but don't worry. We never felt other than safe and everyone was very friendly. Really nice Coffee bar right next door and it was excellent to start each morning with a shot of espresso with the local.
They communicated well with meeting up for the check in but one thing I will have to comment on is a separate contract (very basic one btw) you have to make. It is a local requirement we were told but would have helped to know beforehand.
We would recommend this stay to our friends and family.
