Andreas's place is in an amazing location. Walking out the front of the building the Duomo is directly to your right. Around the block is amazing shopping if that is your goal. Andrea and her son were incredibly helpful in getting our bearings of the city and marking places on a map of specific interests we had.
The apartment was clean and spacious. There was a kitchen, though we never used it as we were enjoying the amazing food in Florence! Great place to stay and great host!
