My stay at Marcia's place was wonderful. The pictures from this listing are accurate, and the view of Cristo Redentor is wonderful. The whole patio is really nice with lots of plants. I enjoyed having coffee there in the mornings.
If read through the listing, you will see that the staircase is a shared space. As someone who prefers private space, I was curious about this, but it was not an issue at all. Marcia made sure I felt free to come and go as I pleased at any hour of the day/night, and I never saw her once when leaving/arriving. The "shared space" is hardly a shared space, and my whole experience was completely private.
Marcia was also very kind and helpful. She would send me a message every now and then to check in and see if I needed anything, she would leave out fresh towels for me, and she even sent me some helpful suggestions for things to do in Rio when it's rainy.
Check-in and checkout were extremely easy. I recommend this place.
