If you want to be in the center of it all in downtown Florence - this is the place to stay. Within few minutes walk to every main attraction and very conveniently located. Apartment is in the building that used to be a convent for women - you can feel the history and yet cozy with modern touches to feel right at home. Fully equipped kitchen, coffee to make etc. Mario and Niccolò were wonderful hosts. Mario was waiting for me at the building to check me in and even went out of his way to help me out with AC travel adapter that I forgot at home- Thank You so much.
Downtown Florence is not exactly the quietest place (it is buzzing even at night), but apartment windows are not facing the main street so it isn't a big problem.
Overall it was a great stay, would recommend it to anyone, especially first timer to explore Florence.
