This is great for college students who want to visit Florence on a budget. The staff at Leonardo house is friendly and available. The rooms are simple as you are really paying for the location. You can not be more central in Florence as you are a five minute walk from all of the sites. The house is private and the rooms are safe - there are deadbolt locks on the doors. However, my room did not appear to have a fire/smoke detector and alarm. Again, perfect for people on a budget looking for simple accommodations.
P.S. You will need a three pronged Italian converter as most of the outlets are not compatible with the newer two pronged plugs.
