Casa Beleza is one of the Santa teresa B&B's (pousada, here). It is very pretty and the owners manage it well; it's also very good value for the money. Good choice!
the ex-Meridien (in Leme, next to Copacabana, but not on the beach) was to become an Iberostar but that deal fell through. It is now vacant but there are rumors it will be refurbished and reopen under some brand or another within another year or so. It was a nice property; I hope it returns.
