Cristiana's place is perfect when visiting Naples. It's in the heart of the city, an awesome pizzeria (with huge queues in front of the door), a well equipped local store, and a pasticceria with awesome coffee is within 1 minute.
The apartmant itself is gorgeous, it's even bigger then on the pictures. The place is quiet, the beds and pillows are really comfortable.
Cristiana was really kind when we met, she organized a private taxi from the airport as well (BTW: the airport is within 1 hour walking distance, in case you are not in the mood of taking part in the crazy local traffic in a car :-).
Really recommended!
