Overall a great stay - place looks amazing and the location is only steps to the Ponte Vecchio and all of Florence! Super chic design (though a tad dark even during the day TBH).
My only two comments that you should be fully aware of before booking are:
1. The sleeping loft - while super cool, the room is really dark in the middle of the night and the stairs tricky when you have to go to the bathroom in the middle of the night! Some under the stairs night lights would be super helpful as the first night almost missed a step at the bottom.
2. The windows are not double paned, so because of the location and street, there's a lot street noise. We generally kept the AC unit running for some white noise which did the trick.
Other than that, amazing place!
