I had a difficult time in London so here are the tricks
– for Airport Hotels (Hoppa Bus – 5 GBP per person at the driver, or 9 GBP 2 ways, valid 2 month)
search for your terminal and hotel here (there are a lot of pages)
https://www.heathrow.com/file_source/Heathrow/Static/PDF/Transport_and_directions/Hotel_Hoppa_timetable.pdf
search for the bus station location on the last page on this link (timetable also included)
https://www.nationalexpress.com/media/1325/heathrow_hotel_hoppa_timetable.pdf
– for London Central Hotels get the train
