Can recommend staying at with Elvira at the "Michelangelo apartment - very central".
The communication was very responsive and the location of the apartment is great with just 100 meters to a few meters from Galleria dell'Accademia. There are many narrow stairs to climb to get to the apartment but it is worth it as the view of the Duomo (Cattedrale di Santa Maria del Fiore) only some 300 m away is stunning. I love the sight during night when the Duomo is lit up. Thanks for a great stay.
