Isabella, who manages this apartment, was so welcoming and spoke excellent English. She provided great recommendations and information upon arrival, including for an amazing gelateria (Vivaldi - check it out!) Yes, the stairs are formidable after walking around Firenze all day - don't forget the 4th fl in Europe is an American 5th fl (and felt like more at the end of the day). In spite of this, I recommend this apartment highly if you are in at least decent shape. The space is the perfect size for a couple. The air conditioning is cold, the hot water is hot, and the wi-fi was the best I found in Italy. We cooked dinner once and the kitchen was perfectly stocked with pots, pans, etc. The location is both central and quiet (since you're on the 5th fl). Would happily stay again!
