My sister and I had a great stay at Karina's apartment. The best thing about it is the location (walk to both Ipanema and Copacabana beaches) as well as the building's doorman, we felt very safe. Karina is an excellent source for information on where to eat, drink, shop etc. Her suggestions were great and she always responded to any questions in a very timely manner. I would definitely stay here again if I am lucky enough to return to Rio!
