Barbara's place was a great experience for my 4 days in Florence by myself! It is the perfect size for one or two people and in my opinion had everything I needed. The pull-out bed was surprisingly quite comfortable, and the air conditioner was a huge plus in the heat. The apartment is a 7-10 minute walk from Piazza del Republicca and a super short walk to the train station (SMN). Some pubs on the street outside were loud some nights, but nothing too extreme. Would definitely recommend this stay, especially if you are looking for something not necessarily directly in all the action of Florence.
