First of all, I would like to say that Rafael is indeed a great host. Whenever we needed some additional info, he was there to help us; he answered our questions on WhatsApp promptly and helped us with his recommendations and tips.
When we arrived, Rafael's parents met us at the apartment, greeted us, gave us all the basic info we needed and showed us the apartment. The apartment itself is really nice, large and comfortable. Two big bedrooms, two bathrooms, kitchen (with all needed appliances) and living room.
Location is also great: one block away from Copacabana beach, three blocks away from the metro station. Hotel is also nearby so it was not hard to find taxi.

High recommendation!
