Amazing on all counts! Mirko (who works with Riccardo) greeted us by the apartment at the time planned and gave us many helpful suggestions. Even prior to the stay, before we arrived but after I booked, he was very helpful with any questions I had about Florence. I know it may differ depending on when the next people are arriving, but he was able to let us have very late checkout, which was amazing!
And the place, well... could not be beat!!! Cannot say it enough! The terrace is even more beautiful than it looks like in pictures. Wifi, a/c, etc... all the basics worked great too. No issues at all. There is also a full kitchen should you need that (though we were too busy eating everything else!). Couldn't imagine a better place to stay!
