Flaminia's apartment is GREAT! Her description is very accurate and the pictures tell the story in full. The interior is very spacious and well equipped with everything you need for a stay in Naples. Just compare the cost and space of a typical European hotel with an apartment like Flaminia's and the choice is obvious.
Flaminia was very prompt with communications - this was our first experience with Airbnb in another country so it made us feel confident about the situation that she was prompt in getting back to us when we had questions. Her brother lives right next door to the apartment and he was our contact point when we arrived - he was very friendly and showed us the apartment and gave us some suggestions for restaurants and so on.
One thing to know about staying in Naples - Any bustling residential neighborhood in Naples is going to be a little noisy (motor bikes, people chatting and/or shouting etc) so if you are a light sleeper this might bother you some. We got used to it pretty quickly. Keep in mind this is not a negative thing on Flaminia's apartment, I believe it would be the case in any apartment in a residential neighborhood.
Overall a great experience and we recommend highly!
