Lavinia's place is all about location, location, location. Walkable to everything! The things we loved:
Location
Host was great and met us upon arrival
Can walk with your luggage from the train station
The things that you need to know if you book this property--there's no air conditioning, so if you are travelling to Florence in the summer months, it will not be comfortable. It was 100 degrees in Florence the days that we were there, and the apartment did not cool down.
The other thing I'd like to point out is that there was a washer/dryer here--which was so helpful for a family that had been on vacation for 10 days. Definitely a plus. Oh, and Lavinia prepared this entire book of information of where to go and what to see that was AMAZING and so helpful!
