Elvira's flat is a great place to stay when visiting Florence. Her associate Giota gave some of the best recommendations for seeing Florence through a local's perspective.
The flat itself is very nice and cozy, one caveat would be this the 5th floor unit with only stairs so just be aware you will have a bit of a walk up. Also, the bathroom is narrow and backs into a v-shape, which could be difficult for a larger person.
Otherwise, you will love this spot, the location is terrific for all that Florence has to offer and the flat itself served everything that I wanted. Would definitely stay again.
