Myself and my partner (both in our 20's) were a bit dubios about staying here over New Years 2011/12 when we had read the reviews however I must say it was lovely.
Our room was on the 17th floor overlooking the city, very spacious and clean. The staff were excellent and friendy, very helpful and either spoke english or immediately found someone who could.
We did walk around Rio on our own and found there to be no problems - which was suprisingly considering it was the week of New Years and we'd been told to watch out for pickpockets.
The Hotel organised a tour for us around Rio - which was far better than the one I did previously and our bathroom even had a jacuzzi!
The resturant food and room service were both good filling meals and although the alcohol in the mini bar in our room was quite expensive everything else was reasonable and value for money.
Whilst it was in Centro and not on Copacabana we found yellow taxi's to be very reasonable - approx R$ 20 a trip. Not bad at all!
Would defiantely go there again - really great hotel.
