I stayed at Ana Karolina’s for 3 nights during the carnival. She was always very responsive with any questions I had. Unlike some of the reviews, the apartment was very clean and pleasant. The bed was relatively harder than typical mattresses, but I had very comfortable sleep every night! Ipanema is a great location to stay in Rio, but the apartment is on a block that had quite a few homeless walking around. Other than that, I had a perfect stay! I highly recommend.
