I think everywhere I've ever lived has had a load of physical books, even if these days I probably majority-read ebooks. I also like soft throw blankets and at least one comfy sofa.

Doors that shut, and enough space that everyone can be on their own behind a shut door when they need to, makes it a liveable home, given the combination of personalities we have in this household. Wifi, kettle and microwave contribute greatly to everyone's comfort.
