We stayed at the apartment for 3 nights and had a good time. It was very clean and spacious (even big enough for more than 2 people) with a terrace. Location wise, we were a 20-25 minute walk from the centre of Florence and although this was not the closest it was still very easy to get to. It was a convenient 10 minute walk to the train station. We hired a car on the last day and it was great since the flat had a parking space.
Chiara was very helpful in giving us tips on where to eat and what to do in Florence and driving around in Tuscany, which helped us plan our trip well.
The only small downside to the flat was if you were to cook, there was not much crockery in the kitchen. However, I'm sure if we had told Chiara this there would have been a solution. Overall an enjoyable stay!
