I only stayed for one night, however I can say that I would stay here again when coming back to Florence! Check in process was extremely quick (even though my booking was last minute), and being able to leave my bags until 8:30pm the following day was a huge bonus (my train back to Milan was at 9:15pm)! Bonus apartment is only .4 miles to Firenze SM station, so I was able to walk with my luggage to station.
Breakfast was very European (breads, cakes, fruit, meats & cheeses and coffee).
The room itself was very clean and the bed was one of the most comfortable I had stayed in for weeks.
