In retrospect, having a Business class lounge at a temperature 3-4 degrees hotter than the rest of the airport is unnecessarily cruel. 

Our flight was delayed about an hour so we had less than 2 hours  

We landed in Florence close to 3PM and we had a food tour scheduled at 5PM. Just enough time to fetch bags, taxi to the hotel, shower, and walk to Piazza della Signoria for the start of the tour.
