I am going to Florence in the fall - first timer. I am not a huge museum buff but would like to visit a few (2 or 3). I would like to spend the rest of the time leisurely walking around the city and exploring the neighborhoods. Would 5 days be too long and would a day trip be recommended to Fiesole, for instance? Also a foodie, so any trips to the tuscan country side that are worthwhile? Thanks so much for the help!!
