How to do with the interior walls?

[Felde]

Hello!

We have a summer cottage from the 1920s. We are renovating a room and are a bit unsure about how to proceed with the walls.

Probably the best is to use drywall, but it might be a bit difficult and messy. Any other tips on how we can tidy up the walls in a nice and smooth way?

If you don't want to skim coat everything, a spackling and a renovation wallpaper provide a good result.

Yes, that's probably where we'll end up

Are you going to paint or wallpaper?

Haven't really decided yet, but leaning towards wallpaper
