I stayed for a week for work (and doing a tiny bit of tourism) during the winter off-season, and everything was superb. Great precheckin communication, and Eliana, who was onsite was fantastic and super-helpful. The location is also great (24hr doorman), with a supermarket right across the street, and being 2 blocks to Posto 5 of Copacabana. Sadly, due to some crazy work deadlines and not great weather, I didn't get to enjoy much of the more fanciful amenities (didn't even turn on the hot tub, which was outside, or the projector), but I did make copious use of the internet/wifi, which clocks at 60mbps down and was light years better than my poor coworkers' connection at the Sheraton, so definitely worth mentioning!
