For those of us who live in Florence and walk around the centro (downtown area), must constantly adjust our daily routines. I didn't know that Florence welcomes over 12 million visitors each year, but at some times during the year it is much more crowded than others. The crowds in the peak periods can be overwhelming and the temperatures right now are not only high--in the 30's Celsius (90's Fahrenheit)--but when the sun hits my skin, it can be unbearable.
