We arrived at 2 AM in the morning and Gustavo had already advised the doorman to be on the lookout for us. The doorman let us in the building with no problem and getting into the apartment was a breeze. The apartment is located close to both Copacabana and Ipanema beaches, a very easy walk to either one.
The microwave stopped working while we were there. We communicated to Gustavo and he acted immediately replacing the old unit with a new one. Each and every time we needed anything, Gustavo replied to our needs and made us feel welcome.
I would highly recommend Gustavo's apartment to anyone interested.
