Room was as advertised. I will say this is the most professional looking AirBnb I have stayed at, easily on par with a mid rated Hotel. Everything was clean and well kept. The kitchen area appeared to be well furnished even though I didn't use it much.
Despite the bed being a couch bed, it was surprisingly easy to deploy and is quite comfortable, easily rates as a solid replacement.
Host was also very communicative and was constantly in touch, though I never personally met them. Check in instructions were very well written and easy to understand, smooth experience.
I would say the only downside to the room is a lack of good curtains, meaning the room is well lit even at night, and proximity to major thoroughfare means its noisy all night. If you can look past those two minor issues, it's a great stay and well located to exploring Florence.
