The “Maracanã” room (you do know about the Maracanã stadium, right ??) is a private room with 1 double bed and 1 bunk bed, so it’s good for up to 4 adults.
Bathroom is inside the room (ensuite private), it has air conditioning, black out curtains and gargantuan lockers for each one of the beds.
It’s located on the 2nd floor of Tupiniquim.
