Waking Up To A Stranger In Your Bed

Paul Drecksler was tired from his trip to Miami. He was in town to officiate a friend’s wedding and had gotten an Airbnb. When he got to the house he immediately crashed out and went to sleep, only problem he was in the wrong house! Thankfully the owner of the home was pretty cool and told Paul that his actual Airbnb was next door. No charges were filed because Paul did break in, but my question is how did he get in undetected?
