Never again
A friend and I stayed here during a recent business trip. We disliked the hotel so much that we left Florence a night early. We both had bad colds, and the room was either so hot that we couldn't sleep (windows closed, no air conditioning), or so loud that we couldn't sleep (windows open). The room was small and dark and unappealing. The staff were unhelpful and borderline rude, definitely not even remotely attentive. During the day, since we weren't feeling so great, we wanted to spend some time lounging in the hotel and reading and people watching; the bar was dark and uninviting. It was too cold and rainy for the outdoor rooftop, and except for breakfast, the restaurant was locked until 7:30, so we couldn't sit and enjoy the beautiful view of the city. The only good thing that can be said for this hotel is the location.
