We had a good time at Caesar Business Botafogo. I really recommend it. It was the best accommodation option we found in Rio at the rate we were willing to pay. The rooms are quite large and comfortable and some of them overlook Corcovado with Christ the Redeemer. It is also close of the underground station, and within walking distance to Sugar Loaf (Pão de Açúcar).
So, taking into consideration the other accommodation options in Rio, I think this one is quite nice. Rio is too pricey, however, and the rates they charge over there are certainly different from other cities in Brazil, especially regarding hotels. But anyway, we enjoyed it, in special due to the free late check out provided to us.More
