Or, frankly, stay in Central London near Paddington and jump on the Heathrow Express which is quicker than staying near the airport and relying on the bus to get to the terminal.
Having just stayed at the DT, I can't say I recommend it. If you want a Hilton property, stay at the Hilton at T4. Sheraton and Marriott all have properties nearby that are within the Heathrow Free Flow zone for local buses. The Renaissance (a Marriott Property) has some nice views of the airport.
I'd say if you have any sort of hotel status, stay in that chain, otherwise the Hilton at T4.
