First, the apartment itself-- it's HUGE (the pictures really don't do it justice) and extremely well equipped with a full kitchen, dishwasher, two bathrooms, and a whirlpool tub-- there's even a smartphone with free SMS, calling and data for you to use during your stay! It's also in a very charming historical building in the very centre of Florence, literal steps away from the Piazza della Signoria. Second, Diana is the most professional and organized host I've ever had, on top of being very friendly and welcoming. The book of recommendations she compiled is genuinely very useful, and both check-in and check-out were a breeze. The next time I'm in Florence I will definitely stay here again.
