Overall, I had a really good stay with Betty.
Betty was very kind and accommodating as she received me in in the middle of the night (2:00am) despite notifying her at a very short notice.
The flat is located in a safe area and there is a 24h reception which made me feel very safe. The flat itself is very clean and organized. The kitchen i fully equipped so that I was able to prepare my own meals.
Good location - close to restaurants, shops, Copacabana beach and a metro station.
If I'm in Rio again I will stay there again for sure. For this price it is a very good value for money.
