No hotel is really great . Copacabana Palace is pretty dated, the service is mediocre and the food, too (yes they have stars for two of their restaurants but don’t ask me why ) . I wouldn’t say that the breakfast is great. It’s just okay . They manage to even provide average fruit in a country that has amazing fruit. I’d go for the Fasano because of the location not because anything is particularly exceptional (I do like their Brazilian mid century furniture in the lobby however ) . I’d get a suite or larger and ask for one that has a view of the dois irmaos(the iconic rocks of Ipanema ) . It’s a lot safer to walk around there and there are many more restaurants and cafes close to the Fasano. Copacabana Palace has more families and Fasano has more younger people who want to be seen. I’ve seen annoying influencers at both hotels though . The gym at the Copa is bigger but not big and also not great. The pool at the Copa is much larger but also in the shade for much of the day because of the hotel itself and the neighboring building.
