Luna is so nice! We communicated through text message and she replied right away. The building is 3 stories, the airbnb is the entire 2nd floor (she gives you keys for the front door and one for each half of the apartment (it is split in half by the common staircase). The only other people in the who building is Luna and her family. They live above the airbnb. They are very quiet! We just kept our doors open the whole time and walked freely between the two sides of the apartment. You need to walk up 2 flights of stairs, so this probably isn't for you if you have big suitcases. We traveled with a baby and they had a pack-n-play crib available for us. They also allowed us to leave the stroller at the bottom of the stairs at the entrance into the building. The location is amazing! 4 minute walk to the Livraria Lello (famous bookstore), 8 minute walk to Sao Bento train station, like a 2 minute walk to a famous tour (I don't remember the name), also near to the crystal palace. We walked everywhere from her house, we didn't need public transit. We also walked across a bridge to a beautiful viewpoint to watch the sunset and saw a few churches along the way. The apartment is beautifully decorated and very comfortable for a home away from home. The kitchen is fully equipped (we cooked all of our meals in the house) and they have a single burner portable stove on the countertop. It worked perfectly for us. We traveled with 4 adults and a baby and there was plenty of space for all of us.
