We stayed here for 5 nights. Overall we had an excellent stay and would recommend this place. Really great & convenient location - within a 6-minute walk to the Florence SMN train station, 6-minute walk to the Duomo. The room was spacious and clean with high ceilings. The photos are an accurate representation of the room.
First-time guests may want to note that this Airbnb is on the 2nd floor above the Bottega Quattro store, and it has a BLACK/BLUE building number sign. We got a bit lost finding the correct building because there is another building about 2-3 doors down the street that appears to have the same building number but in RED. (Apparently in Florence, there are 2 separate building numbering systems - black/blue numbers for residential addresses, red numbers for commercial properties.)
If you are a light sleeper you may want to bring earplugs or ask for the room not facing the street - you can hear recycling pick-up noises (e.g., clanking bottles) and loud conversations from the street. Also, if you are in one of the connecting rooms separated by a locked door, you can hear your neighbors talking through the door. These noises may bother some people, but we were rarely in the room so it wasn't a big deal. And it was worth it for the great location, cleanliness, and price.
