If there is anyone in your group who is mobility-impaired, then I would not recommend Parione Roof Terrace, given the stairs to climb to get to the unit. Having said that, for us it was great. The adults took the upper floor and we had our privacy from the kids in the lower rooms; we had our own bathroom and tv as well. There are two bedrooms downstairs and a pull-out sofa if you have a larger group. The rooftop patio is a very nice touch, either for an early morning coffee or end of the day glass of wine. The downstairs bathroom was very spacious with a roomy shower.
The unit is very well located; it is within walking distance of the train station, Il Duomo, the Arno river area, and a number of
restaurants, a grocery store and other sights. It is on a quiet street, and the unit was also very clean.
In summary, I would definitely recommend considering the Parione Roof Terrace for your next visit to Florence.
