The apartment is beautiful! modernized yet maintained its character and charm.
The outer front door, and inner door to the building can only be accessed by pin numbers then stairs to the second floor (considered the 3rd floor in the US). The apartment has everything you could ever need to stay there for an extended time e.g. fully equipped kitchen, comfortable sitting room, bathroom and bedroom all fully equipped with appropriate and comfortable furnishings.
We could easily walk to popular sites, or take the metro which was only a few minutes walk away. Many fabulous bakeries and a farmers market also within a a few min walk.
We loved our time there!
