I stayed in Paulo's apartment for 1 week. The house is exactly as the pictures. It's a small place but was perfect for us because we only went there to sleep. Very clean and everything was quite new. The apartment has a first aid kit and it's something I've never seen before. It has a water purifier. Bed is very confortable.
I really recommend staying at Paulo's apartment if you want to be safe, comfortable and have a good time in Rio.
