@Kaitlyn70 FYI : Flat sheets are kind of an American thing, they're not very common in most other countries. In New Zealand, just like in most of Europe, the standard is a fitted sheet plus a duvet with a washable cover.
But pillows are also default - it would be weird if the host isn't offering those. What was displayed in the listing? Was the place previously reviewed?
Is the unmade bed the same size as the other one? I mean, if sleeping with a view is really important to you, I guess you could move the bedding upstairs. But I think the better approach is to discuss this with your host - and for best results, try to avoid mentioning refunds or calling the room "crappy," unless you're prepared to vacate the premises and find somewhere else to sleep.
