Nathalia has the perfect Rio apartment. No need for AC, strong breeze, stunning view, cool room layout and architecture, beautiful and cool architecture in every direction, and fully functional and solid kitchen and bathroom with no fake frills.
I've lived in Rio before so I can say pretty confidently that if you're looking for places in this price range (and maybe even higher) this is probably the ideal apartment you'd want to live in if you lived in Rio long term and knew the ropes.
It was also a lot quieter than we expected given how central it is.
If you're planning on working remotely and need rock solid wifi, double check with Nathália about the state of the wifi when you book. The cable modem / router is old and probably needs replacing.
