This apartment is perfectly situated. A short walk to all the great sites in Florence. The stairs, all 65 of them, are seemingly daunting, but doable, unless you really have problems with stairs. If you don't have problems with stairs, they are quite doable. Be prepared.
The noise from the streets below can be hit and miss. Some night more than others.
We almost missed it, but in our laziness on our last night, we ate at the restaurant right downstairs, Buzzino. What an incredible find. Not to be missed. It has been there since 1844. Wow!
If you have a car, definitely follow Donna's instructions to get to the parking garage. It made a big difference and it is right around the corner from the apartment. The attendants know her and were extremely helpful.
