Margharita is a perfect host. She waited for us despite delayed trains and when we finally arrived she had only good words for us. She's very open, cheerful and quite helpful also.
As to the apartment itself, saying it's "comfortable" would be an unjustified harm to the place. It's much more than that. High ceilings makes it really spacious, wooden furniture and decorations gives you that real feel, on the other hand - windows opening at the inner yard garden give you desired silence despite high proximity to all city's landmarks. There is also a huge bathroom with a shower and two sinks. The only thing it lacks is kitchen, as it is under reconstruction at the moment. You won't probably feel it though, thanks to splendid breakfast and dinner places app 20-30 meters from the apartment. These are not only insanely tasty, but also quite cheap as for Florentian standards.
Nothing more to add. Highly recommended place... and the host.
