For our first experience with Airbnb, we stayed 5 days at Francesca's in April.
The place is really charming : a typical building, a nice room and a nice view !
Moreover the flat is really well located : 2 minutes from the Drassanes station, 5-10 minutes from the historical city center (barri gotico).
Francesca is an excellent host. She welcomed us at our arrival and took time to explain us the best places to visit, to eat, to have a drink, etc.
Also she is fluent in english, spanish, italian.
