You can't beat staying across the street from Copacabana beaches. The apartment is chic with nice touches here and there.
they provide beach towels and travel soap which was a nice touch. the group running the Airbnb is a real estate firm so there's a corporate impersonal feel. My check in involved a group chat with 5 members but only one sent me a PDF of check in instructions.
beyond those vibes, the apt is great if you wanna be close to the beach, Ipanema and a short walk to the Metro.
