Talk about a meddling houseguest.
An Inner Sunset district man came home Wednesday to find that a stranger had taken a shower, moved around furniture and packed his belongings into a suitcase, police said.
The 33-year-old woman had allegedly entered the apartment through an unlocked garage door at the building in the 1300 block of Fourth Avenue.
Cops responded and arrested the woman, a Reno, Nev., resident.
She was booked at Park Station for burglary, police said.
