A guest space feels cared for when it answers small questions before they are asked. Think about a place to charge a phone, set down a glass, hang a coat, and find an extra towel.
Shape the room
Use a lidded box for spare linens and a small card with the Wi-Fi name. A single framed print or branch is enough decoration when the useful details are already present.
Let it earn its place
Hospitality is often a sequence of tiny permissions: put your bag here, sleep late, take what you need.
