Marcelo's been a great host. He met us earlier than the agreed check-in time and was very quick to reply to any of our questions. I would suggest his place for people who have to work from home, like we did from his place. His wifi is great, the room with the air conditioning as well. Everything was clean and we were comfortable at all times.
I truly recommend that neighborhood and street. There are several 24 hours drugstores, there are grocery shops and the subway is a 7 min walking distance.
Whenever I go back to Rio, I will make sure to stay at Marcelo's place again.
