Once you have reached London, you can go about by taxis, buses, or by underground. I like the underground because it is rapid, easy and cheap. There are so many cars and buses in London. The underground is usually quicker than taxis or buses. Because there are so many taxis and buses that one can’t drive fast. If you don’t know London very well, it is difficult to find the bus you want. You can take a taxi but it is more expensive than the underground. On the underground you find good maps which tell you the names of the stations and you can find your way easily.
