We stayed in Gloria's flat for 4 nights and loved it. It was by far the best value we found for accommodation during out trip, and the interior exceeded all our expectations.
Gloria was a great host, very responsive to messages, and gave us plenty of tips on what to do in the city.
We mostly walked to and from the center, and didn't have any problems, it is quite straightforward and we knew the route well after one day.
Overall, I would highly recommend Gloria's flat for anyone looking to explore Florence from a comfortable and relaxing base.
