Well located apartment (however, accessing it could be problematic for people with reduced mobility as they are stairs and the apartment is on top of a long slope).
Carlos greeted us on our arrival and gave us a tour of the apartment. I was afraid before our trip that we would be cold in the apartment as it said "no heating" on the advertisement but Carlos reassured me by explaining that there were a reversible A/C that sends hot air back in all the rooms and the living room (and that was indeed the case).
The apartment is quiet and really close to all amenities (metro, supermarkets, restaurants, etc. within 2-4 minutes walking distance).
The only drawback is the cleanliness left to be desired at times: the carpets in the living room and bedrooms were dirty (probably due to previous travelers) and the curtain in the bathroom was dirty and moldy at the bottom. It could easily have been changed for a cheap price.
But in general everything went quite well. I would surely recommend that apartment, subject to the points mentioned above.
