This is a small two-bedroom-hall-kitchen apartment in Flamengo, which is a neighborhood 20 mins away from both the beach area in Copacabana/Ipanema, as well as the historic center. The apartment is right next to the metro station and on a main road, which made the location great. That also meant, however, that it was quite noisy both early in the morning and until late at night.
The host, Erika, is fantastic -- very helpful in every way. We didn't meet her, but she was super quick to respond to messages. She left us a map and other brochures about Rio which was very kind of her.
We were 3 in our group, and found the size of the apartment to be adequate.
There is no air-conditioning in the apartment (mentioned in the listing) but more importantly, there was only one small table fan in the entire apartment (no ceiling fans). Rio in January gets quite hot so there were times when we were sitting in the living room sweating profusely!
The rooms are smallish, with little storage space. The kitchen is quite large and had all you may need to make tea/coffee and make a simple meal. Erika let us use the washing machine which was a bonus!
