Well, i have to put in order the positive sides:
1- Great, great location. It's in the hearth of the city. Two minutes walk to every major locations like Duomo, Palazzo Vecchio, Piazza della Repubblica etc.
2- The place is gleaming and hygienic.
3- Facilities of the place in adequate.
4- Monica is kind and thoughtful.
5- Sleeping under that ceiling is exceptional.
Negative sides:
1- No balcony. This is the only disadvantage of the place (for smokers only :))
This place must be definetely the first choice if you want to visit Firenze.
