We were picked up from the airport and driven to the apartment. All went smoothly. We also took the transport back to the airport and all was smooth.
The apartment itself was just like in the pictures. It was also clean. The location is excellent if you like partying (in Barro Alto). If you like more quiet environment, this might not be for you. It is quite noisy even after midnight (at least on weekend). Note: no lift.
All in all: totally recommended.
