Alessandro and Amanda's place is in an fantastic location: just footsteps from the Bargello( go! its great and not over crowded) short walks to Piazza Santa Croce, Piazza della Signoria and The Uffizi..
Its located on a quiet street away near some good restaurants where you can dine and feel like a local.
An added bonus, just a few blocks away is an automated luggage storage place, where you can stow your luggage should you decide to stay past your check out time.
Alessandro and Amanda made check in/check out easy. They were very responsive and able to share some great recommendations. The space is small but suitable for 1-2 people ( you're in Florence- spending your time visiting amazing sites-how much space do you really need)? The bed is really comfortable and shower has good water pressure. All in all, a great stay.
