Marcos (even thought he was on a business travel) checked in with me as soon as I arrived to his apartment. He made sure I had everything I needed (wifi, water, key, etc). He answered all the questions I had to explore Rio and gave me some really good suggestions what to do in Rio. The security at the apartment was great and I was able to leave the key whenever I went out. I love his place since it's so close to Leblon beach and all the restaurants, supermarkets, drug stores around it. I highly recommend anyone to stay at Marcos' place.
