The pickup address provided by Zuzuche was incorrect, which led me to the wrong location. After contacting them, the rental company sent someone to pick me up and take me to get the car. The rental location was very far from the Heraklion port. I originally planned to walk to the port after returning the car. Due to the new return point being very far from the port, walking there was not possible, so I had to pay an additional 10 euros to the rental company for someone to pick up the car from the port. Additionally, the car wasn't provided with a full tank of gas, which was inconvenient as I had to be very cautious not to overfill the tank each time I refueled.
