I had a lovely stay at Andrea's place. His Airbnb is really clean and comfortable, and having a nice en-suite bathroom was such a nice addition. The Airbnb is situated in a friendly neighbourhood, just beside a small daily market and another weekly market. It's a few steps from the Arno River and about a 10-minute walk from the city's tram line to get to the centre, which were both nice qualities during my stay.
Andrea was very friendly too, as he offered a bunch of great, not-so-obvious recommendations for Florence and made me feel comfortable. I felt so bad because I kept having to delay my arrival time, but he stayed communicative and friendly, even though my transportation to Florence took so long and I arrived late.
I would definitely recommend Andrea's place if you're looking for a comfortable, appropriately-priced place to explore Florence.
