We stayed at Marco and Patrizia's place for three nights and it was perfect. The apartment had everything we needed for our short stay, was very comfortable and very well located. We enjoyed the fact that it was close to the train station and that you could basically walk to the historic center quickly.
Marco was very accommodating and very nice with us, as we were late two hours because of a train delay.
I would recommend this apartment to anyone wishing to have a comfortable stay in beautiful Firenze.
