Su is very communicative and hospitable! I arrived at 2am, already super tired, but she had given me specific, detailed instructions with checking in beforehand.
Even though I arrived very late, she was able to meet me at the door. Airbnb is an an easy walking distance from Terminal 4, and is a great place to stay if you have a flight to catch at Heathrow.
Oh, and seeing the nice sign with my name upon entering the room is a nice touch. Thank you Su!!
