My family and I flew up to Iguazu for two nights during our trip to Argentina. Grand Tourbillon was affordable, and they had 'family rooms' (three single beds for us 'kids') which was very nice. The rooms were of a decent size, and had balconies overlooking the pool. The rooms felt clean, but pretty worn, and the shower didn't get warm until after it had been running for 30+ minutes (don't worry, two of us took cold showers). There is an included continental breakfast, which was pretty good (and unlimited), and we ate dinner one night in the same restaurant, which was okay. Buffet style, nothing special, but easy and filling after a day hiking the falls. Despite the hotel building being average, the service was exceptional. The front desk was very responsive, and helped us to schedule cabs to the falls, as well as a tour for our second day of an amethyst mine (which was very cool, actually). Overall, I would recommend this hotel for a budget-conscious traveler. Just know, you won't be getting any luxury!
