If you're looking for a space near the historic sites, this is a good place but the location was not what we expected, a lot of climbing hills and stairs to get to the apartment. We were excited to get to Florence but when we were trying to get the apartment, the host kept pushing the meeting time back because they were "busy," it was very difficult for us the first day because we had to drag our suitcases everywhere and couldn't venture too far because we thought we were meeting soon and then they would change the time on us. And, when they did arrive, they seemed very annoyed that they had to let us in and show us around, very unfriendly with us. They were helpful though by helping my pregnant wife carry her suitcase up to the 5th floor. Lastly, it wasn't until after they left did we discover the toilet did not flush - you have to use the toilet, shut the lid, stand on it, reach through the cupboard that held the toilet tank and manually lift the flusher from inside the tank (I hope you are not short) - very inconvenient for our group. The space was clean except for a giant ball of hair in the bathroom.
That being said, it isn't their fault how the old building is laid out, the place was big enough for 4 of us comfortably and they had all the accommodations one would require.
