We had a great stay at Jeanne's place by Leblon. We stayed in an apartment just behind her house with incredible views of the ocean below! It really is breathtaking. There is a roof terrace to capture sunrises in the morning. It is a 10 minute walk along the cycle path to town and there is a nice patch of beach across the road by the Sheraton Hotel (it has a lot less people than Ipanema or copacobana). The apartment itself was great. Bright and airy, clean, spacious with fridge/cooking equipment in the kitchen and a refreshing shower.
Jeanne is a very friendly and helpful host too. We can't recommend that her place highly enough! Obrigado, see you soon!
