Michele's/Max's place is absolutely stunning and was great for 3 of us. Huge apartment, highly secure, beachfront (posto 10), perfectly situated in the most luxe part of Ipanema 1-2 blocks from Leblon. (The LV store is on the same street... not that you'd want to go there in Rio). Amazing juice and brunch places very nearby. A block from Baby Brasa (pop-up gym on the beach every morning, like a Barry's Bootcamp). The apartment itself has two A/C units in the living room (very rare in Brazil!), a/c in every room, complete kitchen, multiple TV's. Very comfortable bed. FANTASTIC maid service at least once a week (and she'll do other random stuff for you as well).
Max is super responsive, and provided concierge-level assistance -- he recommended personal chefs, masseuses, spa/beauty places, other excellent local advice. (Max must be a local celebrity, because the salon owner couldn't stop talking about how great he was).
Stayed a week, wish I stayed longer!
