Thank you very much Rosella, for your hospitality!
The flat location is fantastic: walking distance from the main Florence attractions and from the central train station. As we arrived in the morning, Rosella waited for us at the department before scheduled check-in hour. All instructions were clear and useful, the flat was clean and the window had an anti-mosquito net ..(this is worth mentioning, as in another airbnb flat the mosquitoes bites and marks were annoying).. Definitely I would stay again in Rosella's flat if I visit Florence again.
