If we ever return to Naples – and it's such a vibrant and rewarding city that it's something we most definitely want to do – we wouldn't even bother looking for anywhere else to stay.
The apartment is faultless, and if you want to be in the heart of the 'action' in the historical centre, then I don't see how its location could be bettered. Step out into the street and it's all there in front of you: the inimitable theatre of frenetic Neapolitan life in the raw.
Our welcome, and the overall hosting, was perfect.
