We had a good stay at Bianca's unit. The unit was extremely spacious! I would think more than 1000sqft. Photos were accurate but the unit did feel a bit more dated than the brightly lit photos. Bathroom especially could use some renovation. The host provided some juice and milk when we arrived, which was a nice touch.

Location was fantastic. It was close to train station, a few minutes walk from Santa Novella square (where we saw a French market during our time in Florence!), and within walking distance to all the major sights like Duomo, Uffizi gallery, etc. The restaurant just around the corner (Centopoveri) was also good and cheap, with a big local crowd.

Drawback of the location was it was directly atop a bar, so during weekends it was noisy, especially since people lingered outside the bar late into the night. Despite being on a side street, cars and garbage trucks drove by late in the night. There is also no air conditioning so you cannot really shut the windows to keep the noise out (closing the windows didn't help much with the noise anyway).

Note that the unit is on the top (4th) floor, and like most old town buildings, there is no elevator. Stairs were narrow and winding so it was a huge effort to move our luggage up into the apartment. There is also a 5GB/week limit on the Wifi usage, which I thought was fair.

The host was responsive (and perfectly fluent in English) when we communicated through email/Whatsapp. But when we arrived, we were met by a friend who did not speak English at all. We had a bit of difficulty understanding the added tax that needed to be paid and what amenities were in the apartment.
