Martina's place it was perfect for us. Very well located: just at the entrance to the Galleria dell' Accademia, 3 minutes walking to the Santa Maria del Fiori Cathedral (Duomo) and 10 minutes walking to the train station (Santa Maria Novella)
The studio it was exactly like in the photos, very clean and cosy, just perfect for a couple.
We strongly recommend Martina's studio.
