We had a great time in Florence and at Chiara's place. It was very accurate to the description and in a great location. Florence is a very walk-able city and we were within a 5-15 minute walk of most of the sites in Florence. We could even walk from the local train station with our bags past the Duomo which was a very breath taking view just minutes after getting off the train. The neighborhood was quite and safe. Communication beforehand was great, and she helped with our many questions. There was wine and breakfast available when we arrived which was a nice touch. There is also maps and a bunch of recommendations for location, affordable restaurants and markets. We would recommend the local market and specifically La Botteghina Dell'augusta (great meat and cheese selection).
The wifi worked great and we were able to clearly skyped with love ones back home. I'm sure if we wanted to stream a movie there would have been no issues.
I would highly recommend La Casa di Grata and would stay here again if we visit Florence.
