What a great place ! Everything about the flat was all we could have hoped for, such a homely feel with attention to details, comfortable beds, tastefully decorated, close to the historic centre... and right by a market (which by the way we really appreciated with a special recommandation for the delicious fresh pasta - porcini ravioli... mmm!)
We arrived 8 hours later than planned (our plane was blocked by snow) but Mauro kept in touch with us and still came and fetched us even though it was midnight. He was very friendly and welcoming, giving us advice, and enthusiastic about Florence. (Et il sait très bien parler français, parfait pour nous !). Thanks also for the complementary bottle of wine.
We had a slight problem with the heating, Mauro was ready to come round and take a look but in the end it sorted itself out. Once working properly the flat was plenty warm enough.
There's a great bakers just close by and a nice bar, and all the main sights are within walking distance.
I highly recommend this place and the welcome you receive !
