I spent almost 3 months in the studio and I have enjoyed every single second.
It's perfectly located: very close to transports, restaurants, supermarkets and sightseeing. 10 minutes by bike to Copacabana beach, 20 to the Ipanema one.
In the past I have lodged both in Ipanema e Copacabana and I fet Botafogo to be safer.
The studio has averything you need, very clean and silent.
I will definitely try to book it again on my next trip to Rio.
