I spent a lovely time in Florence in the apartment hosted by Antonio and Laura. It's really in the heart of the city, so everything was within walking distance - the duomo, the river Arno, Ponte Vecchio...
The room was cozy and clean, so it was easy to feel at home very fast.
At the time of my arrival I also got a few tips what to see in Florence and the area around, which were quite helpful.
I have to say it was an absolutely great time in Florence.
