I had a great time staying at Márcio's apartment. It was the perfect location, right in the middle of Lapa, yet managed to be just enough out of the total craziness to actually get to sleep. The place has everything you need and Márcio made himself available to solve any problem should they materialize, but none did. If you decide to stay here you won't regret it. The place is close to the metro, the Lapa arches, and a short walk from most everything you'll need. Hopefully the next time I'm in Rio the apartment will be available for me to rent again :-)
