The appartment is quite small - one room + a second with bath/shower/toilett - but very cosy and the interior is lovely, you just can feel that everything is kind of hand-picked by the owner. Although there is a couch in the main room i would not recommend it to use it for more than 2 people - i would get kind of overloaded ...
What we liked most, was the location: within short distances walk (10 - 15 minutes) you reach the main attractions like Ponte Vecchio, the Duomo, etc.
