It was our first Airbnb booking and it was a wonderful experience : everything was perfect.
Warm welcome from Fernandino with nice attention (Prosecco, water, beer in the fridge), very useful wireless wi fi device and umbrellas. Nice touristic advice with maps, restaurants...
The apartment is very quiet and comfortable (special mention for the large bed). All this : 5 minutes walking to get to the Duomo.
Don't miss it!
