This is where the US-vs-rest-of-world DT schism really comes in to play (and most bad apples in the US ruin it for a few good DTs) but in the US DoubleTree properties tend to have a much higher level of visible "stopped giving a damn" than the rest of the HH portfolio -- exteriors that are weathered and may have been last pressure washed let alone painted at some time during my lifetime, but not likely more than once, landscaping maintenance that just barely exceeds what is required to avoid a city code enforcement or brand standards violation. Door hardware (particularly on exit stairwells) that was last sold in 1975, sloppy paint jobs that look like they were done by a drunk maintenance guy who was simultaneously unclogging the toilet, elevators that look like the last time their interior was overhauled was sometime prior to the Nixon administration. Outlets that have been abused by enough travelers that anything you plug in will fall out unless you move a nightstand to keep it jammed in, etc.
