This is a wonderful flat in a great location! It's more central than you might think from looking at the maps, a perfect home base for exploring the city (complete with powerful a/c to combat the Florence summer). It IS a third-floor walk-up, so you'll want to consider that if anyone in your group has mobility issues, but it is truly beautiful and exceptionally well appointed.
David was a terrific host! He met us at the flat right on time, showed us the ropes, and left us with maps and suggestions for restaurants around the city (he's right about where to find the best gelato!). You won't be sorry!
