Before starting the review, i would like to say i have been using Airbnb for the last 7 years, staying in multiple places worldwide. It's my first time I had to cancell an apartment after arriving to it. I have to recognise the fotos are true, but the reality it's completely different, the place is dirty, smells very bad, the curtains are black, full of mosquitos, etc.. I consider myself a really romantic Airbnb user, what happened to me is a clear example of people who only want to make cash from this business (actually the owner has more than 5 flats for rent in Rio) and are 0 concerned about minimum standards for guests.
I cancelled the flat, lost my money, had to go to an hotel, that´s the truth despite the opinion of the owner.
Final recommendation: stay away
