I stayed at M&C's place for 2 nights and had a good stay for two reasons: firstly, C was a very good and very welcoming hostess. She was available on the day I arrived Firenze, and oriented me to the map of Florence, shared very good tips on where to eat the best gelatos, best vintage furniture shops, where to hang around for the sunset and explore the city by simply walking. She mentioned how small the main city is and that outside the 'tourist spots' is better to see. She also made breakfast for all, including another girl staying at her place.
Secondly, C is a co-traveller. I liked her openness, sharing her thoughts and feelings about working and living in Italy. She interacted and communicated with us very openly, made us feel like we are all travellers in a small world.
Her place is well situated near the Central station, which makes it all worth the walking!
