We had a great time in Firenze and at Ettore's place - the location nearby the centre is really great, you can walk to the big cathedral in a few minutes and have stores and restaurants just around the corner! Also the couch/bed was surprisingly comfortable and the flat as a whole provides everything you need. You even have a washing machine, some books with useful tips for the city etc.
The neighbourhood was calm even though the city centre is not far away. Ettore also answered superfast when we had questions and helped with everything - all in all everything fine and a nice play to stay :)
