Day 263: How to create a cool vibe?

Look, I found a new place for all the brochures and maps for Uppsala in the bookshelf (they used to be in the kitchen). My plan is that this will make the guests feel more welcome to use the living room as well. I really want them to feel at home, which includes reading in the sofa. It would be more fun for me too. The guest that arrived today said the place has a "cool vibe", which sounds great. But I'm still trying to think of other ways that will make the guests feel more welcome, let me know if you have any suggestions!
