Tetris

Design-wise, this hostel in downtown Foz – a 20-minute drive from Iguaçu Falls – really stands out from the crowd: both unisex and gender-segregated dorms are housed in shipping containers, stacked like Lego bricks around leafy garden spaces. Wooden pallets serve as sun loungers next to a tiny pool, and every surface is painted in candy shop colors. Toast your stay with the free daily cocktail offered, and consider bringing a blanket in winter – air conditioning keeps things cool in summer.
