NSA has received positive feedback for its friendly and professional staff, who ensure passengers are accounted for during border checks. Many users appreciate the pleasant travel experience and express willingness to recommend or use NSA services again. However, some reviews mention delays in arrival times due to external factors like traffic jams and customs procedures.

Me and my fellow passenger had a bit of a nightmare at customs between Brazil and Paraguay. Embarrassingly, we know very little Portuguese or Spanish so has no idea what was going on. We basically needed another Brazilian stamp. Our driver, managed to explain to us what we needed to do, organised for a Brazilian police officer to take us back to the border, all the while reassuring us through this worrying time. He went above and beyond to sort out this issue and still managed to get us to Asuncion on time! We were seriously impressed with this driver.

Nice on time. Drivers were good. Good help at the border. The recline of seat could not be stopped. Water drops out of the tv fell on clothes. No airconditioning, soo all Windows were fogged. No vegetarian meal. The toilet was disgusting. Smoke of the drivers could be smelled on top floor.

The service was on time and even arrived before it has been scheduled. The bus was super comfortable.

Generally fine. One time, very helpful at passport control. Comfortable, but a bit too cold and draughty

It would have been helpful to know the traffic to get into Brasil could de as terrible as it was. Was late by 2.5 hours and by the time we got there I missed getting to see Iguaca Falls.
