Excellent value for money.
I felt very safe and comfortable.
Some of Rios best restaurants are close by. There is a nice little park (Praça Nossa Senhora da Paz).
The apartment is on the first floor so if you want to keep the windows open at night you should buy one or two electronic mosquito repellents.
If you are extremely noise sensitive: There is a slight humming from a converter (for the AC) in the bedroom. You will only hear it if the AC is off (I stayed here in winter). Raíssa bought me an extension cable so I could keep the fridge running while turning the electricity switch off at night.
The window goes to the back yard. It is usually very quiet. Only during football games will you hear some people cheering. During summer you may hear the AC units humming.
