Let me start with this: Francesca is the absolute best host you will ever meet in your life. She is a legend. Very friendly, extremely communicative, always replied to our messages within minutes, constantly happy to provide us with tips and ideas about things to see and do in Naples. She made our holidays so much better and easier.
As for the flat itself, I can say without hesitation that it is perfect for Naples, regardless of what you're planning to do, or how long you're staying for. It is freshly renovated, and very tastefully so. It is very big, spacious and comfortable, and even better than it looks in the photos. The location is ideal, in one of the main streets of the city, close to everything in terms of mass transport. It's spotless, and has everything you can think of in terms of equipment, and even if there is something missing (I can't think what), Francesca will be there to provide it. I really don't think you can find better accommodation in Naples at any price point, and we would refuse to stay anywhere else other than Francesca's next time we're in her wonderful city
