I can only confirm all the previous comments on this place. Clean, neatly decorated, easy communication (in Eng, Italian and French), quiet and safe area in the city center, the best vfm one could find.
Additionally, I need to say that my sister and I visited Naples with the aim to look for an apartment, a task more difficult than we thought. Maria and Stefano have been extremely supportive and caring, going really out of their way to help us and we would have literally never managed without them. Their psychological and practical support has been extremely valuable to us.
They are both the best proof of the famous Mediterranean hospitality and both my sister and I are very grateful to them.
I could not have chosen a better Airbnb for my stay in Naples.
