London Stansted is located quite far outside the city centre of London, but due to the large amount of passengers arriving to the airport, it is easy to get from the airport to the city centre. Here you can find some of the easiest solutions:
1) Stansted Express (train)
The Stansted Express train leaves from the airport every 15th minute and reaches Liverpool Street within 45 minutes. This train also stops on Tottenham Hale and Stratford where it is connected to the underground.
