Jacqueline greeted me with a wonderful smile. I found everything exactly how it was pictured and presented on Jacqueline's airbnb page. I would say that in fact, if anything, it all exceeded my expectations. Paula Freitas Avenue, in this last block, is a safe place in Copacabana, and, I shall add, I found Copacabana and Brazil, overall safe: surely much better than you may have been lead to believe.
Nothing bad happened to me at all.
I would surely love to rent Jacqueline;s place again: it was beautifully decorated, beautifully situated (between the beach and the Cristo Redentor, and a mare couple of blocks from the most beautiful subway station I have ever seen in ANY country: Cardeal Arcoverde, majestically dug in the rock and dramatically lit), and Jacqueline made me feel at home in that there were snacks and water waiting for me. I could not figure out the air conditioning machines very well, but it was me: I know they worked, and I used them occasionally and with great enjoyment. BTW there are TWO air conditioning machines in the apartment: so you shod NEVER worry about ever being hot in Rio!
