Soraya and her assistant on the ground (Johnny) were both very hospitable, friendly, and communicative. The location itself was perfect: in the center of the city right across from the Ponte Vecchio. The apartment itself was also relatively clean with a great shower. Additionally, Soraya called me a cab to take me to the airport upon my departure which I greatly appreciated.
Nonetheless, I did encounter several issues during my stay. First, the apartment was not cleaned from the last guest that stayed there prior to my arrival. Although Johnny was extremely apologetic and personally cleaned the apartment as quickly as he could, I did have to wait a bit before I could enter. Second, the bed is advertised as "king-sized;" however, in reality it is two twin-sized beds pushed together (since I noticed a crease in the middle of the bed). Third, the heat in the apartment did not function properly for several days. Again, even though Johnny could not have been nicer about apologizing and attempting to fix the issue, I did go without heat for a few days. Last, the apartment itself is above the restaurant on the ground floor. As such, the elevator to enter the apartment is in the back of the restaurant right next to one of the tables where people dine. I personally did not have a problem with the elevator placement, but future guests should be aware of this awkward feature of the apartment.
Overall, the apartment's prime location, its overall quality, and Soraya and Johnny's hospitable nature outweigh the aforementioned issues. I definitely recommend this apartment to future visitors of Firenze!
