London is a very big city and it is very easy to get around using the Tube or buses. The tube map is very easy to decipher and makes it easy to work out how to get where you want to, that is if the tube lines are not shut for maintenance.

BEWARE: There is no warning to say that you are signing up to a paid service. It only tells you after you have confirmed your phone number. Then it’s too late, and you will get sent the SMS for the route you were researching. Each text cost 25p and the one that they sent me was incomplete. It said 2of2 and had one line with a postcode and nothing else.
Also on the site, there is no way to make a complaint about this incomplete service. So I would advice you not to sign up and just print out the route or get an A to Z.
