What’s the best way to get from Heathrow Airport to London Liverpool Street Station with two huge luggage?
I know I have a choice between the Heathrow Express and the Tube.
a) I can take the Heathrow Express to Paddington and switch to the Hammersmith Line.
Or
b) I can take the Piccadily Line to Holbourn and change to the Central Line.
But I want to take the option that allows me to avoid staircases. Any idea which option suits me the best?
