Spent the week of Carnivale at this apartment with 7 other adults. Perfect location with very friendly and helpful building staff. Great for Carnivale as close to the parties in Ipanema and the subway to get to the Sambadome. Good pool area and great view. Great restaurants nearby. Much cheaper than 4 hotel rooms in the same location. 8 would be the maximum number of adults for this unit.
A sofa bed could be of assistance for larger numbers. Ideally would be better for a smaller number or if some were children. I would certainly return. I could happily live in this apartment!
