If we could put 6 stars (instead of 5) we would have.
Very luxurious with many stylish details. The lighting, the space, the design, everything is very well thought. The bed is the best bed I have ever had (even in 5star plus hotels)... Remarkably comfortable. You can even see Santa Maria Del Fiore from the living room.
It is very well located too. Close to the center shops (less than 5 minutes walk) and yet not very far from the car rentals agencies and parking (ZTL boundaries) should you wish to road trip across Tuscany.
Easy check in and great service from Mary.
Truly, it is very hard to find a better stay in Firenze. It was better than what I expected when I made the booking (after hours searching airbnb, trivago and Expedia) . My advice to you hunting for an accommodation in Florence. Stop your search. You have found THE apartment.
