We were looking for a nice and comfy place as a base camp from where we can visit the center of Florence and this place fitted perfectly. It is very close to the train station and a couple of blocks from El Duomo. From there you can basically walk your way everywhere.
We stayed there with two kids, and they loved it. The rooms are wide and open with light filling the space. The apartment was as you can see in the pictures, but even more beatiful on the spot. The only drawback is that you have to pay those top windows with quite a few stairs to reach the top of the building.
The apartment was provided with everything we needed. A nice small kitchen and a smartly refurbished restroom. We only have a small mishap when using both the dryer and the AC together, making the general switch set off. Fortunatelly, Alessandro explained to us where to find and restore the electric switch (and he probably warned us about the limit on the electric use during his nice reception, but we didn't remember it).
Overall, very comfortable and definitely a place to recommend.
