Maria's mansarda is exactly as shown in the photos. Perfectly clean, confortable and has a very well equipped kitchen. It's a 8 min walking to the metro station and it takes at least 30 min to get to the city center what could be annoying sometimes. The bus stop is right on the corner. Near the apartment there are two supermarkets, a bakery and a pharmacy, although this is a residencial neighborhood and has a lot of immigrants, I felt perfectly safe.
Maria is a wonderful host. She answers quickly any questions and resolves any issues as soon as possible. She even offerd to take an bring me to the subway station at arrival.
I would stay there again and highly recommend for long stays.
