Without knocking this sad, dated and oppressive building down altogether and starting again, it's hard to see how they could improve this classic Heathrow airport hotel more than they have.
I've stayed there a few times over the last decade or so, and it is now better than it has ever been. Very efficient reception, a much cooler cafe/bar (with table service!) and improved rooms.
Excellent value for park and fly, but as we found out, not so great for terminals 2 to 4 as the shuttle only goes to T5.
