I spent a beautiful month in Arabella's and Paolo's airbnb. The welcome was very warm, Paolo picked me up at the train station and helped with my luggage. The whole time leading up to the stay (and during it), they were very proactive in communication and full of local suggestions. The apartment is very well equipped, including all the kitchen appliances and tools one could need. The location is 15 min by foot away from the Duomo and 3 min away from the train station. During the colder months (I was there in November - December), the studio can get a bit chilly, but with the ac/heater, that wasn't a problem. In the end, I had to pay extra for the electricity bill, but that was discussed between us beforehand.
Thank you both for my nice stay in Florence, I'm excited to come back there sometime in the future!
