We had an absolutely incredible stay at Arianna and Luca's apartment! The views are incredible - waking up to the rooftops of Florence and views of the Duomo was unparalleled. The apartment is centrally located - no more than a 15 minute walk from most museums, art galleries, or other attractions - as well as the train station. The apartment was clean and comfortable - the shower had great water pressure, the AC worked well, and there were small touches, like a bottle of wine in the fridge, that made us feel even more at home.
Check-in was (relatively) painless. Luca was super communicative and there to meet us and help with our luggage. Yes, there are stairs - 115 of them - but he helped us carry our suitcases! Taking the stairs was actually a good way for us to stretch and work off all of the pasta, cheese, deli meats and wine we ate during the day. :)
If you're okay with stairs, I would absolutely recommend this apartment for your stay. By and far one of the most special spots we've stayed at during our travels!
