In my 20s, I was traveling with friends on a shoestring budget, and we stayed at the absolute cheapest hostel we could find that was close to the downtown area so we could spend as little money on public transit as possible. “Hostel” was a generous term.
It was a tiny brick building in the center of a large city block, so you basically had to walk through this narrow urban canyon to arrive at its featureless metal door. You just punched in a code to enter. There was no one on-site to greet or help you in any way.
So. Many. Ants. There was nothing you could do to avoid feeling one crawl across you in the middle of the night, so trying to fall asleep was like torture. The manager/owner was completely unhelpful and insisted that the traps they’d already placed were good enough.
If we’d been able to afford any other option, we would have left after one night. Sadly, we spent four nights in this nightmare and just used it as an excuse to stay out all night exploring. A horrible experience, but it was a true moment of bonding for my friends and me.
