Everything was great

It felt okay overall, and people in Sydney seemed generally nicer than those in Melbourne. I got a free upgrade to a Mitsubishi Outlander when picking up the car, but during the inspection, I noticed a nail in the tire. They replaced it with a Nissan X-Trail instead. When returning the car, I was worried that their 8 AM opening time might be too late, so I followed the instructions at their office to return the car at the Andrew parking lot next door, only to find they charged me AUD 45. I was speechless, but the service itself was fine. In hindsight, waiting for Apex to open and returning it there would have made no difference in reaching the airport on time. I suggest choosing basic insurance and then upgrading to full coverage for AUD 349 at the car rental location—the total cost is roughly the same. PS: Roadside assistance will cost AUD 250 regardless of the situation. Parking fines are very expensive, so make sure to follow traffic rules and check the signs!

Very satisfied!

Although it's not an international chain, the service is still good, and there was no upselling.

Excellent car and experience

Like: Pick-up was efficient and friendly. The airport shuttle service was very convenient and our driver, Leonardo, was friendly and full of useful recommendations for our time in Sydney and the Blue Mountains. He also got us to the airport in plenty of time for departure. We rang ahead to say we our flight was soon when it came to drop-off and they were ready and waiting in the car park for us and had everything was ready to check and hand back. We will definitely be using Apex again due to the excellent and friendly customer service.
Dislike: Nothing - we were happy with every aspect of our rental experience.
