I highly recommend Leonardo’s apartment! It is incredibly close to the train station (less than 5 minutes), easy walking distance to everywhere (about 10 minutes to the Duomo), and it is a wonderfully comfortable and cozy spot. The back porch overlooking an enclosed group of courtyards is a gem, and the heat lamp was a big help in February. Leonardo left thoughtful extra touches (croissants and crackers, juice, coffee and tea), and left a very thorough information book for guests. He is also very communicative and quickly responsive, and he was so generously flexible with us in the midst of train changes and delays. I would definitely stay again!
