We have many Fae in our house. We have an actual "portal" in my ritual room that goes to the Otherside. It is one of those cute "Fairy Doors" you can buy at garden shops, with windows. When I hung it (close to the floor), I told Them that They are welcome to come and go as They please. The tree out front of our house is also a Fae Tree.
I call the Fae "Otherkin", as that is what They have told me what They are.
They often like to be mischievous, hiding things, or taking shiny things. I have a shrine to Them, with shiny things, a piece of Connemara marble, a piece of Blarney stone, a tiny tea set with milk and honey for Them, crystals, flowers, a light, etc.
I had a friend sleep over after our Imbolg ritual last night, and she said that room (which is where our futon is for guests) is Otherworldly. She also said she could feel Them in our house very strongly.
They like it here, because we treat Them with respect, and don't presume They are little pretty girls with wings (some are giants, some are like tall humans, some are small and dirt covered....so many, just like human beings).
Just be respectful (remember, They are powerful beings), always give Them offerings, and accept Them as They are.
