I highly highly recommend Tina's place for your stay in Florence. It was close to the train station, less than 10 min away and she provided very clear directions, and super central to the markets and shops yet off the main road so you get some calm. She was extraordinarily gracious and well-prepared with maps and recommendations for a local's view of Florence. I cannot emphasize enough how much of an easy walk it was to main attractions such as the Mercato Centrale, Uffizi Gallery, Gallery d'Accademia, Palazzo Vecchio, the Santa Maria church, etc. Everything. Her room and the apt are nice and spacious, and she helped me with my suitcase up the 3 flights of stairs. You'll be fortunate to stay with Tina!
