What is the worst experience of staying in a hotel?

I went on a business trip with my colleagues and found a cheap hotel, which was very small. This place is only big enough for a bed, and the bathroom is pitifully small. When I was washing, I bumped into the wall. What I can't accept most is its poor sound insulation. The following people make it very clear that it is particularly noisy at night. Those people were eating, drinking and having fun down there, which made me lie in bed gnashing my teeth and want to hit them, but I couldn't do that, so I fell asleep early in the morning at night, which led to being late for meeting customers.
