I stayed in Ethel's apartment for 2 weeks as I wante to extend my stay in Rio and it was perfect. The apartment is just as described and with all the amenities needed in the kitchen (cutlery, oil, mixer, toaster etc) and the bathrooms (plenty of towels, soap etc).
I really appreciated how quiet the apartment was as I was working from home. The terrace is perfect to have meals while enjoying the sun and the hammock in the living room was an added luxury.
The building also has 24h security and location is litery 6 minute-walk from Copacabana beach. The bus and metro are also a couple minutes away and there are restaurants and supermarkets on the same block. I will definitely rebook when I'm in Rio next as I felt safe and cared for.
