I loved staying here! Everything was so clean and spacious (it was just me) and you couldn't beat the location. I was pleasantly surprised at how safe I felt there going there just by myself. I also loved that it was super clean and had everything I needed.
The only things to notice are: the bathroom makes a little bit of noise when you're using it, but I had no problem with it. I actually like it when bathrooms do that. And the other thing to notice is that although you can't beat the location, that also means that you're in a very popular zone and that it will be noisy outside. There was one night it was really difficult for me to sleep but this had nothing to do with the hotel, it was more the people outside yelling all night and street cleaning. Nothing a good pair of earplugs didn't fix the next night! :)
All in all, I highly recommend this Airbnb if you're looking to explore Florence in a very centric area and in a very good hotel. I'd definitely stay here again.
