Very easy to check in since there is always someone at the front desk (up one floor) from 8:30am to 7pm. They said that they are reachable by email and phone anytime as well, but we did not need reach them after hours since everything ran smoothly. The elevator is small, but we are thankful that there even is one since most places in Florence did not have one. Although it is not "central AC" there was an AC unit in every single room that worked well in the 90 degree heat. Location is great as well, about 10 min walk from the train station (west) or the Duomo (east), and just a couple blocks from the Arno River (south) and the Piazza Santa Maria Novella (north), with plenty of restaurants in between. Overall, a great place for a large family to stay in!
