Hometown girl from North Carolina, US! Twenty-six years old and I adore traveling, history, and am currently in medical studies in my local college, while working at the University of North Carolina Hospitals!
After keeping the flat tidy for two weeks, we made one last cleaning round for almost three hours the morning that we left, making sure the place was nice and clean. The only thing that was 'dirty' was the bedsheets, which we had used for two weeks, and imagined would be washed by Nadia, since there was a cleaning fee charged to us for staying.
I believe the statement on Americans and cleanliness is derogatory and rude; on top of that, only one of the three girls staying was actually American.
I'm actually surprised by this feedback, since the only time we actually bothered her in two weeks was to let her know one of the neighbors came over yelling at us because the toilet was broke and making a noise on his side of the wall.
