We were in Italy for 2 weeks and Residenza Castelli was the B&B that provided us with the best and memorable experience.
The location of the property was absolutely central. The shopping alleys, museums, major landmarks and restaurants are literally just below the B&B.
The room was spacious for two and the shower facility was great. There was also cleaning provided daily.
The hosts Lorenzo and Gio are absolutely hospitable. Not only did they help to iron out our travel issues (we had to cancel our B&B at Cinque Terre due to a train strike) so we don't incur cancellation costs, they were also very helpful with recommendations on where to eat, shop and what to see.
If you are looking for somewhere convenient and safe, and would like to have a friendly and helpful host who is always willing to lend a hand or give a suggestion, then Residenza Castelli in Firenza / Florence is the only B&B you should go for.
Thanks for such an amazing time Lorenzo and Gio!
