i was staying at márcio’s studio for 2 weeks. and i highly reccomend it. great place to stay in rio de janeiro, 6 minutes walk to metro station, close to parties in lapa on weekends (what is great advantage) but very safe. walk distance to museums and other interesting places in centro, 15 minutes walk to quiet beach. and márcio is really great host, thank you one more time for your help! i hope i will come back there.
