Sabrine was a special guest, from the beginning when she arrived until she left. When she arrived at the airport she expected me to leave the key at the "reception" (obviously she confused AirBnBs with Hotels). I offered her possibilities to leave her luggage in safe lockers in several locations, but that was obviously to much effort. My (Hidden by Airbnb) arrived at 9.30pm after the university and showed her the flat, etc. and offered her to show her and her friends the cultural aspects of Barcelona, but that was not really important for her.
When I returned I found about 25! shopping bags, full of trash in my room, several empty water bottles under the couch and the glas desk has now several deep scratches. I felt a little bit like a housekeeper for very young, spoiled kids who doesn't know how to behave when they are guests. All in all Sabrine was an unpleasant guest, but I wish her the best for her future and good upcoming journeys.
