Overall, it was fine, but the wait time can be long during busy periods.

Alamo was extremely unpleasant. During car pickup, the receptionist seemed to intentionally delay by persistently promoting additional services. If you refused, they would keep staring at the computer or nagging endlessly. To avoid delaying my next schedule, I reluctantly agreed and ended up paying double the cost. During the vehicle inspection, they were nitpicking as if using a magnifying glass to find issues, almost as if wanting to make up a fault to charge extra. Thankfully, I drove cautiously, and nothing went wrong. It increasingly felt like a scam, so I decisively canceled my subsequent car rental plans with Alamo and switched to Avis. To highlight the main point again: Alamo in London is terrible!!! I've uploaded all the documentation to prove the situation is true.

Booked whilst standing in the Alamo premises que, due to an issue with another car hire company ,But the company policy meant I was made to wait 2 hours before being allowed to pick up the car. Even though it was ready to be picked up immediately.

Pretty good

Small cars were not available so I was offered a bigger car with no extra cost. Super helpful and friendly staff who do not mind talking through the whole car with you.
