I have two things to say about Vittoria:
1. She is an awesome host. Met us at the apartment in the middle of the day to accommodate our train schedule and spent a good long time talk with us about Florence. A super sweet, smart and welcoming person. 100 stars.
2. Vittoria's apartment is the best airbnb I've rented in Europe. Having stayed throughout Spain, France and Italy, Vittoria's place is without a doubt the nicest I've experienced. Anyone who's travelled in Europe knows there are certain inconveniences you have to accept about well located lodgings (awkward layouts, less than perfect access routes [like narrow, long stairways], puzzling plumbing, etc.). Vittoria's place suffers not a single one. Totally new and rebuilt interior with two large, modern bathrooms. Logical layout and damned good design sense. 99 stars.
