In London, you can enjoy endlessly not only sights, but also roads. So I advise everyone to hire a car. Of course, after returning to Russia, motorists begin to feel mildly depressed. At least I have. I often visit the capital, visit my daughter at the university, and without the car in any way. By the way, I only use the services of this company. They and the prices are pleasant, and the terms of the agreement are adequate.
