There are about four Hiltons around Heathrow. We stayed at the Hilton Heathrow Terminal 5 in 2015. We often stay out of the hotel if we have an early flight out. Usually we try to get a later flight stay in the city. This place is slightly off the beaten track. We managed to organise an accessible van to take us to the terminal. A plane takes off and flies over the hotel every 45 seconds but the soundproofing is good. The room was a bit poky but okay. Restaurant was quite nice. It had an elephant.
