Marcia's place is AMAZING! Very well located and close enough to 2 of the best beaches in Rio. 5 min walking distance to Copacabana and about 8 min to Ipanema. Many restaurants and entertainment options. Subway is pretty close too, even though I didn't use it. The building is nice, and very secure. The doorman is always smiling and nice. No curfew. The apartment itself is cozy, with air conditioning and a fan. Kitchen has everything. Shower has good pressure, very nice after a whole day on the beach. Bed was super comfy. If you're coming from outside of Brazil, you may need an outlet adaptor for your electronics. I bought one in one of the many stores close by.
I recommend this place to anyone. You won't regret it. Lastly, the place was spotless. Very, very clean! I will come back for sure!
