The place is perfectly located in the centre of Florence, but beware of the steep stairs (appartmenet is in the 4th floor)! Franca's assistant welcomed us and showed around the place. When we arrived the flat was not yet ready due to previous guests' delayed check out. Hence we agreed on a later check out as well and had to go for a walk while Franka prepared the place.
The flat has everything you need for a short stay. Not as clean as it could be, especially the bathroom. Wifi was available but unfortunately limited to 110 minutes per day and quite slow.
