We stayed in Gabriele's apartment for three days and had a great time. Though he himself wasn't able to do the check in with us his cousin Alessandra showed us around and told us a lot about what to do in Florence. She was super nice and helpful. The apartment is very well located right outside the city center, within walking distance to all the important sights as well as a big supermarket. Also, there are a lot of Restaurants and stores in the same street. I highly recommend the mousse au chocolate ice cream from the ice cream store downstairs! And if you like fresh croissants for breakfast you should get some at the bakery just two houses to the left from the apartment - mamma mia so good!
All in all we really enjoyed our stay in Florence!
