It has been a really good experience to stay at Adalberto´s apartment. Adalberto and his wife were very welcoming and helpful, they gave us very useful tips to go around the city, we tasted his "cafe gustoso", tea and by the way, he speaks very good Spanish. The apartment is just as he describes, very close to Copacabana´s beach, to metro station and is very easy to reach the different tourist destinations from his place.
I will definitively recommend Adalberto´s place. Muchas gracias!
