We had a nice stay at Sonia's lovely home. Light atmosphere, quite spacious, 2 baths plus a beautiful private terrace, it's perfectly convenient for 4 people.
The location is about a 15-20 min walk to the city center (Duomo, etc) but there is also a bus stop nearby. The area though is excellent for food! A lot of well-reviewed restaurants and food shops around to choose from.
Our host, Sonia was very friendly. She personally greeted us when we arrived and were even welcomed with a basket of fruits and a bottle of wine! She explained to us firsthand everything we needed to know but she is also very easy to communicate with after. When we had some concerns or questions, she didn't hesitate to promptly check on it and help us right away.
Over-all, we recommend staying at Sonia's place. Great host, beautiful place, we would definitely consider booking here again when we come back to Florence! Grazie, Sonia!
