Francesco is a very experienced and professional host who goes out of his way to communicate effectively with his guests. What impressed me most was the speed with which he reacted to requests or questions - sometimes we almost got live customer support, which put us at ease and was very helpful :)!
The check-in was uncomplicated and very flexible, as we could check in much ahead of time. The same goes for the check-out, where you just have to leave the keys in the flat and close the door behind you.
The flat has everything you need for a short weekend city trip: one or two double beds; a bathroom (naturally) equipped with a shower and a washing machine; a kitchen (which we didn't use, however) and a kitchen table; and rooftop terrace on which you can spend your nights enjoying a bottle of wine. Don't expect spacious rooms and lavish furniture, instead prepare yourself for a Neapolitan-style fourth-floor modest flat furnished with all the basics and located in a prime spot right in the heart of Naples!
