So, upon advice in another thread, I'm avoiding the Heathrow Express and Heathrow Connect and am trying to map out a trip from London-Heathrow to the closest tube station to where we're staying-- Warren St. Even though the journey planner site accepts my entering Heathrow Terminal 5 and Warren St. as the destination, it keeps giving me a final stop at St. Stephens Gardens, which I don't even see on the tube map. Am I doing something wrong?
