We really enjoyed our stay at this flat on the south side of the Arno. Easy walking distance to shops and restaurants, and not too far from the historic city center. We preferred being in a more typical residential neighborhood because it allowed us to escape the crowds and get some peace and quiet. The flat itself was clean and charming and efficient.
One important note for future travelers: Florence gets hot. This flat has no A/C (which is totally fine) but it's easy enough to cool off by opening the windows and turning on the fans. The downside to this? Mosquitoes! We got eaten alive. This isn't a knock on the place, which we loved, but a warning for other guests to come prepared with mosquito repellant! :)
Next time we come back to Florence, we'll seek out this place again.
