The apartment is very well designed and had everything I needed. Check-in was easy via a lockbox and communication was good. The place was very clean, and seemed to me to be in a safe neighborhood. When the windows are shut it is surprisingly quiet given how loud Naples is. The place is close to a metro stop that connects with the main railway station, but it's also not too far to walk to the main attractions. As noted in the profile and in some of the comments, the spiral staircase might be an issue for people with physical limitations, though I didn't have any problems with it. I had a great time and would stay there again next time I'm in Naples.
