We were informed by Guido the morning of our arrival that the previous guests had broken the toilet in the apt. we had booked, but he had already found a solution and gave us another apt in an even better location. It all worked well with check-in and check-out and the new apartment was of similar size and distribution, clean, functional and in a beautiful spot near Ponte Vecchio, and we stayed there for the 3 days originally booked in the other place. It was a relief to find out that even though there had been an issue he solved it before we were there. Guido also pointed out the nearest supermarket for us and helped with a place to leave the luggage for the last day after checkout. We had a nice stay in gorgeous Florence.
