We traveled here for the Olympics and were a bit hesitant due to us not knowing the area. However, we were pleasantly surprised. It was located in a great location and equally between 2 different metro stations, both within 15-20 minute walking distance. The apartment was clean, easy to access, and met all the needs of our family of 5.
You can see Sugar Loaf Mountain and the Christ Redeemer. One note, the apartment is located at the top of a steep hill, however we found there was an elevator across from the mall that you could take instead of walking up and down the hill.
We would request to stay here again and definitely would recommend it to anyone heading to Rio. Also, the owner is very responsive to any questions. That was a BIG help for us.
