The appartement Manfredi rented us is conveniently located on the island, within walking distance from the port and on the way to the crater.
The appartement itself was not exactly what we expected since it is a pension with several rooms, next to one another. However, it was clean and functional for one night. Make sure you plan your trip (time of arrival with the boat) in a way that matches their check-in conditions for they were not super flexible when we got there at 13:00 (and the room was not ready before 16:00) even thought we had announced our arrival time.
Manfredi is a nice and professional host who speaks perfectly French and shared a good dining recommendation with us (fresh fish).
