Anna's appartment was perfect for us, it's very spacious (we were 7, and we were very confortable) and clean, it's just across the street from the train station and very close to the Duomo. Anna was a great host, we had good communication before and during our stay, she made sure we had everything we needed and was very flexible on our check in and check out time. I strongly recommend Anna's appartment if you plan to visit Firenze !
