First off, this was a very well-designed apartment in a very good location, right in the middle of one of the busiest shopping areas in Firenze. It is renovated, modern, and clean. The hosts are quite responsive and kind. Check in was timely and communicated in advance.
A few things to note - the beds are not queens and are instead two single mattresses side by side, similar width but not the same length as a queen would be. We did not use the sofa bed. The windows are not soundproof with the busy street but it is manageable. The AC also only worked in one of the bedrooms.
These were not huge issues and I would definitely say we mostly got what we bargained for.
