"Do they have an inn?"
Inns aren't just a good place to find a bed for the night. They also serve as the local restaurant, bar, and meeting hall. So when you enter an inn you might find local peasants and tradesmen, traveling merchants, soldiers, and even politicians.
A room in a typical inn is far from luxurious. There is a mattress filled with straw, a jug of water, and a chair or crate to sit on. Windows, which are not guaranteed, are more likely to be shuttered holes in the wall than glass panes. Glass was very heavy and very expensive, and not entirely transparent either.
Many inns are likely to have a common room or bunk room instead of individual rooms. What you give up in privacy, you make up with warmth since individual rooms won't have a fireplace.
The privy, or toilet, is in a separate little house out back. Unlike modern port-o-lets, outhouses typically do not stink. Ashes from the hearth are regularly emptied into the hole, neutralizing the odors.
