Irene is a great host from the start when she noticed our age and asked if we were sure we could handle three flights of stairs. Generally, we went out in the morning and came back in the evening so we only went up those stairs once a day. I don't know if we could survive 4 floors! You get to most of the places you might want to go in Florence within a 15 minute walk. Our longest walk was home from Piazza Michelangelo. There were loads of places to eat about a five minute walk down the street. If you want a place within walking distance to all the sights, clean with decent bed and a great host, this is it. If you are picky, go elsewhere.
