We had a flight out of terminal 3 in the morning, and had to return our rental car to the terminal 2 short term parking garage the night before, which is attached to this hotel. The location is incredibly convenient, it was about a 5 minute walk from dropping off the rental car to the hotel, and then about a 10-15 minute walk to terminal 3 in the morning - no need to take a shuttle (although there is plenty of available shuttles to other terminals within walking distance of this hotel, as well as an Underground station). I would HIGHLY recommend this hotel to anyone flying in or out of terminals 2 or 3, it took so much stress out of our travels not having to worry about commuting and just being able to walk to the terminal in the morning when it was time for our flight. On top of that, the room was very clean and spacious, and had a view of the runway! Will definitely stay here again the next time we fly in/out of Heathrow.
