I would highly recommend Alessandra's place. It is a great location situated in the middle of the city. Walk to the Ponte Vecchio or to the Uffizi within minutes, and from there you can walk to the high end retailers of fashion brands, with loads of wonderful small specialty stores and restaurants as well. Or, discover the area where the Pitti Palace and Boboli gardens, which is within minutes as well. Alessandra was so helpful with all of our questions, it made our stay so delightful!!
