It was a great stay in Rio. Even our arrival in the early morning was not a problem, we were already welcomed, could use the shower, had a nap and then explored the city. The location of the flat at Copacabana was great and we felt safe all the time during the stay. We did not see Frederico a lot, but in advance he answered all the questions via email and every time during the stay we felt welcome to ask.
Expect the cold and rainy weather a great stay, thanks again, Frederico.
