Even when Justin Bieber holes up in a small rural town in Illinois ... he finds a way to live like a king.
JB got sidelined in Hamilton, IL Thursday night when his tour bus needed repairs. Hamilton sits on the Mississippi with a population of about 2,800 -- but Bieber still managed to catch some Zs in a $10k per night Airbnb rental.
Hard to believe the riverfront mansion only has 4 bedrooms, but inside, it's extremely popstar-friendly with arcade games, a gym and even an old school jukebox.
Outside? An infinity pool over the river with a view! Of Iowa.
We're told police had to patrol the road for people trying to get a glimpse of Justin. It's as if he was the biggest thing in town.
