Small, cozy apartement located at the Piazza della Signoria. Barbara was a fantastic host, quick to respond and very accomodating with the check-in. Note that there's barely any phone signal in the building and that the WiFi can be spotty -- good enough to make travel plans and book tickets for attractions, but you won't be going on a streaming marathon here (then again, why would you when there's so much else to do!).
I would 100% recommend the place for anyone looking for a centrally located stay in florence.
