This is a cramped, dilapidated and sad flat that is nonetheless priced at a premium level.
The host is not particularly interested in his guests (he seems to be a businessman with several properties, and not to have any connection with this property), and is curt and unwelcoming. For instance, he delegated the introduction to an employee who was not familiar with the property, there was a 30-minute-plus delay in gaining entry to the flat despite our giving all the notice the host asked for, and there was not so much as a bottle of water provided by way of welcome.
The flat is several flights up a steep and narrow staircase, and this, along with the fact that Florence is a compact city, undermines the value of the flat's admittedly extremely central location, which location is really the only positive reason to book here.
Many of the shutters, windows, and electronics are broken or half-broken.
I would not recommend this flat unless guests are able to persuade the host to offer the flat for at most €60 per night.
Our experience was not terrible, in my opinion (one of my co-guests disagrees), but is far, far below par for Airbnb. There are plenty of better places to holiday.
