The door for the apartment can’t be unlocked from the inside unless you have the key. During my stay, I locked the door behind me when I went to tour Florence. My friend was still in the apartment, but couldn’t get out until I returned with the key to unlock it. The ceilings are very low in several places throughout the apartment (especially the bathroom). The shower also isn’t ideal. There’s no door and it’s just a drain on the floor. There’s a curtain that loosely covers the area around the shower. Expect much of the bathroom floor to get wet.
