The location of the apartment is amazing - walking distance to all the major sites, restaurants, and shops. Right outside of the door is a beautiful view of the Duomo - the location cannot be beat.
I stayed here with three close friends - we each had a spot in a real bed which was nice. The outdoor garden was a nice treat - a good place to relax after walking around the city all day.
The bathroom is small and hard to move around in (though fully functional). With a bigger group though it is harder to manage 5 days in a small bathroom space. It is also not so sound proof...
The owner was so nice - welcomed us at check-in and gifted us a bottle of wine. He was flexible with our times and available for any issues (which we had none during our stay). He also provided taxi numbers and car options since I had an early flight out of Florence and cabs may not have been readily available. Cab service he provided was great and on time.
Overall a pleasant stay in a beautiful city!
