We had an amazing stay at Simonetta’s place. The apartment is super central and all the hotspots are just at a few minutes walking distance. Simonetta is really kind and tries to help you find the best hotspots. She has lot's of tips and really makes sure you have everything you need for a perfect stay in Florence.
The only negative thing we would have to say is that the house isn't soundproof at all. You hear everything in the streets with the windows closed. And because there are a lot of motorbikes in Florence, the noise can get really loud. The first night (a Saturday) we couldn't sleep at all. It sounded like they were having a Hell's Angels party outside our door until around 4 or 5 in the morning. This was the worst night though, the other nights were not that bad, but we still recommend bringing REALLY GOOD earplugs.
That being said, if we would ever come to Florence again, we would definitely consider staying at Simonetta's place again since everything besides the noise was really perfect.
