The apartment is really well-located, nicely decorated and very well insulated.
Only downside though: if it's ideal for a few days with friends or for a romantic stay in Florence, it is not a baby-proof apartment at all (which we assumed since a highchair and a baby bed were listed in the flat equipment). The stairs and the mezzanine floor do not have proper railings (glass or solid fill) which makes it very dangerous as anyone can fell while going upstairs, especially young children.
