We use frequently AirBnB during our trips, but this apartment was the best we ever stayed.
Sparkling clean, elegant, like set-up by a designer (even the dishes matched the courtains and furniture colours), at walking distance to all tourist atractions, and plenty of caffees, restaurants in the neighbourhood (which by the way is safe and elegant).
Last but not least : Giulia and her father are best as regards to hospitability and help.
HIGHLY RECOMMENDED !
