You couldn't find a more centrally situated apartment in Florence, right between the Duomo and the Palazzo Vecchio. The terrace on the roof has magnificent views of both.
The kitchen, bathroom, toilet and Enrico's bedroom are on the same floor; a living room and the guestroom are on the floor above; the terrace is one floor above that. This means quite a lot of stairs (+ one flight of stairs from the latch door to the kitchen floor), so if You have any difficulties moving about this might not be the ideal place for You. There is no elevator and quite a few steps to Enrico's door.
The toilet is in a corner of the kitchen and so tiny that you cannot turn around when the door is closed, which may cause embarrassment. Still, it works just fine. There is a ceiling beam in the bathroom that is very low, so You must remember to keep Your head down to avoid bumps. The guest room is pretty basic, but who comes to Florence to spend time in their room anyway? And the terrace is the crowning glory above it all, be it morning, noon or night.
Enrico is friendly and helpful, but also leaves You alone to come and go as You please.
