Hmmm - dodgy hotels...
My worst was in Nyalam - rats living in the bases of the beds, toilets (such as they were) across a courtyard with a fierce guard dog, and locked in overnight (probably because of the dog). The saggy beds were as nothing.
Then I've had a hotel in Santiago (Chile) whose main business turned out to be as a brothel. In that case the saggy bed had been fixed by putting an old door under the (thin) mattress. The electrics in Chile were generally pretty dodgy - things like warm water for the shower being created by wrapping a naked electric fire heating element round the pipe to the shower head.
Closer to home, I've had a few in Spain - this one (streetview
) did the saggy beds and non-working plumbing, but the food was good even if the formerly magnificent dining room was starting to fall apart, and in one place we got parked in an airless, shabby annexe about 100m off, that ended up with me taking all my bedding up the ladder onto the roof.
I've done a prison cell too, in Namur. The locks had been taken off the cell doors, but the windows still had the bars. Still, it worked quite well - we had the wing to ourselves so we saved money by taking over the dining room and bringing in supermarket beer rather than drinking in bars.
All the French hotels I've used have been quite good, but that's mostly because the hotels were all on organised tours (Raid Pyreneen, 2 x CTC tours & one club tour). If I'm not on an organised tour, I camp.
