Cristina's place was very nice!
Very cozy, very clean and a short walk (15-20 min) accross the Arno to the major sites. We loved staying on the other side of the Arno, with the locals and exploring the lively Oltrarno neighborhood.
Cristina met us at the train station (she works there) and her husband gave us a ride to the apartment and checked us in. The apartment is very cute, on street level so a little bit noisy, but still very comfortable and fully equipped.
Florence is a beautiful city and Cristina's place was perfect for soaking it all in.
