The attic was larger than could be inferred from the photos. There is a living room/kitchen, a bedroom with a double bed and another small room with a double bed up a small stair; our kids (10 and 6) loved it. Of course there was a bathroom with shower etc. All clean and recently installed.
It is located near the center of Florence, which was also the only downpoint: it was quite noisy at night.
The landlady was very nice, which more than made up for the fact that she only speaks Italian.
Internet was intermittent.
