I stayed in Gustavo’s place for about one and a half weeks, and my experience was great. First of all, Gustavo let me check in way earlier than 12pm (I arrived in Rio in early morning), showed me the place and gave me useful tips which places to dine in, where to buy souvenirs, etc. He also kindly provided me with an adaptor so that I could charge devices.
The place was sparkling clean, and it was comfortable to stay inside even in the middle of the day when it gets hot outside. Location-wise it’s nearly equidistant from Ipanema and Copacabana, so both locations are easily accessible. There is a small hill one needs to climb to get to the apartment, but I didn’t find it to be problematic.
Overall, good experience and I’d love to stay there again next time I’m in Rio.
