A perfect location for a stay in central Florence with close walking access to all nearby attractions we wanted to visit! The check in was easy and through the Keesy app and we didn't encounter any problems with this at all. We had good and regular communication throughout from the owner which was very helpful. A bottle of wine waiting in the apartment for us was also a lovely touch.
In terms of any negatives, the apartment is a lot smaller than it appears in the pictures, which was mentioned in other reviews and is accurate. The stairs are very steep leading to the apartment itself in the building so I would advise caution if you or any companions have any joint or mobility issues. The advert does mention a security deposit which the owners expect prior to check in and I felt uncomfortable providing credit card details over email or WhatsApp, however they were happy for me to pay by PayPal and refunded me the day after check out with no problems.
