I had a great stay at Marllon's place, right at Copacabana beach (two blocks from the beach). Lots of restaurants and bars around too.
Marllon's place is perfect for one or two persons. Easy access to Copacabana, Ipanema, Leblon, Leme and other attractions like Sugarloaf Mountain and Praia Vermelha.
Communication with Marllon went very smoothly, he is very friendly and always responded within minutes. Both at check in and at check out he was very flexible and adjusted to my arrival and departure times. The doormen at his place are also very nice and professional.
I will definitely stay at his place on other visits to Rio if it is free.
