There are three chain hotels worth considering:

The Sofitel is located at the end of Copacabana beach and has an excellent restaurant, good rooms and good faciltiies.

The JW Marriott is in mid-Copacabana and is small, but otherwise typical JWM. Don't eat there except for breakfast.

The Intercontinental is in Sao Conrado, on the beach, and slightly tattered but convenient to everything there, including a shopping center with several good restaurants. Still, you'll travel from there to get anywhere.

Rio is one of the most expensive cities in the Americas, and hotel rates reflect that. No hotel is "good value" but you can get decent deals.

There are some very nice and slightly less expensive boutique hotels located mostly in Santa Teresa in the mountains above the central part of the city.

Otherwise the hotels are mostly mediocre or blatant ripoffs like the Fasano.
