Pros: Super friendly Host. She could speak English (which is a big plus in Brazil), she gave us all useful information about the area. She provided us with clean towels (even more than we needed) and linens and even some basic food.
location of the place was very convenient: 5min walk to Copacabana beach and its restaurants, 10min walk to a big grocery store, 2min walk to all local stores and restaurants. it was a nice and safe street. taxi station was just cross the street.
apartment was very spacious with all required services: 2 bathrooms, one extra shower, one equipped kitchen.
Cons: windows in bedrooms were such that couldn't be completely closed so sometimes it got cold and during busy times, like worldcup, got really noisy.
