While I had a good experience communicating with Elisabetta and checking in, overall I wouldn't recommend this place due to several cons.
Cons: The bathrooms were really weird and weren't the pictures in the photos. One is just the toilet connected the bedroom that only has a sliding plastic partition, not a door. This isn't good if you value your privacy. While you'll probably be staying with a SO, I'm sure most will still want privacy. This bathroom also smelled of sewage when we were there. Had to close the partition, but only helped a little. It crept into the bedroom and wasn't pleasant.
The other bathroom has the shower, which was a bit ridiculous. It's has tiny makeshift steps that I had a hard time getting in and out. Definitely wouldn't recommend to older folks, or just people who aren't agile. While the shower room was fully renovated and new, it was still awkward, and needed to place a towel on the floor to make sure the water didn't leak out when showering.
The photos shown on the listing are pretty accurate, but the place is dimly lit compared to pictures. The kitchen is pretty bright but all the other rooms are a bit dim. The floors were also dirty or just looked really old. I wasn't comfortable walking around barefoot. The apartment is old, and I can't fault it for that, but the pictures made it seem so much brighter and clean looking than it actually is.
Pros: Checking in was easy, and host answered questions quickly. The Location was nice, not too far from everything. A little out of the center of the tourist stuff, so a little more quiet, if that is what you are looking. Florence was really walkable, so the location was nice.
Overall I wouldn't recommend this, unless you don't mind the cons that's I've pointed out.
