Antonella's place was very nice - clean, big and with the cutest balcony to enjoy a good book. The location is very good if you're traveling by car, it's a very quiet neighborhood and Antonella's even has a free parking space. But if you want to go into the city by bus, be aware that, even the bus stop being 1 min walk from the front door, during the weekend the frequency of the buses is very low and you may end up waiting more than 30 minutes to catch a ride (like we did).
Antonella is a very nice host as well and was available to help us out with some tricks to visit Florence by car!
On the other hand, breakfast did felt a bit short for us comparing with other bnb locations. Nevertheless, Antonella made herself available to upgrade the breakfast options. Also, if you want to cook there's a 5€ fee for kitchen usage that we weren't expecting. It's understandable but you should have that in mind when planning your stay.
Overall, a very nice, new, comfortable and affordable stay in Firenze - recommended!
