I'm a local from Rio, and I have lived in the city for many years in the suburban district of Barra da Tijuca. This time, however, I traveled with my American partner, so I wanted to stay in an apartment where I could find a mix of comfort and a great location.
Gustavo's apartment is exactly what you'd hope for in that regard. Located in one of the most lively streets in Ipanema, Gustavo's apartment offers a cozy environment and excellent walking access to Ipanema's beach and the Rodrigo de Freitas Lagoon. It is also close to the subway station and Rio's best restaurants and cafés.
I found the apartment's description on the AirBnB highly compatible with what I saw in real life, and you will find a modern studio with all the equipment necessary for basic day-by-day needs. Unlike other people's critiques, I didn't struggle that much with the electric shower. The water temperature was perfect most of the time.
Gustavo and his co-host were very helpful with all my questions
