Unfortunately, I do not recommend staying at this apartment.
The general location is great, right between Ipanema and Copacabana. The building is nice, and the apartment matches the pictures.
However, one thing to note is the apartment being situated directly at the intersection of roads where busses and other heavy traffic accelerate and signal both during day and night. This, coupled with single-paned windows without insulation, make it not exactly suitable for longer stays or for work.
Communication with host was not very effective as after brining the problem to Renata she initially offered a resolution but then stopped responding altogether.
I also suggest paying close attention to the lack of reviews from international visitors and to many reviews from other Airbnb hosts from nearby locations.
