Matteo was very easy to communicate with and was happy to wait for us when we arrived at around 9 in the evening with no problem. He's a very nice and friendly young guy and gave us a nice bottle of chianti as well as some nice restaurant suggestions (although I recommend you call ahead for reservations). The apartment was clean, and in a very co venue to location. 6mins from the train station, 2 minutes from the Piazza Sta Maria, and 6minutes to all the car rental places (like Avis, hertz etc), so if you arrive by train and then hire a car to drive around Tuscany after Florence like we did, you have no problem rolling your suitcase to and from Matteo's apartment. The rest of the city and all its sights are an easy walk.
Whilst the bed was a sofabed, we found it pretty comfortable. Thank you so much Matteo! :)
