I had an absolutely fantastic stay in Silvia's apartment!
The location is as good as one could possibly hope for, just 2 minutes from the centre square with the Palazzo Vecchio and the Ponte Vecchio. The apartment is spotlessly clean and very stylish. There is a wonderful little piazza downstairs where you can get a coffee in a real Florence cafe, and look at the Torre della Castagna and the Casa di Dante right beside your building.
There are supermarkets and other stores very close nearby, and you have a feeling of really being in the centre of the city. It's a 2 minute walk to the Duomo and you can hear the bells every evening, which is astounding.
Silvia is a wonderful host, extremely accommodating and kind. She was always on hand to help me with anything that I needed! The wifi is strong and there is a full kitchen with all amenities to cook. From the kitchen you can see the Bargello and the Badia Fiorentina.
Overall it's a picturesque setting for anyone looking to feel really part of Florence, and I would absolutely recommend Silvia's place!
