It was definitely a challenge to please this diverse group of young, summer interns, especially regarding the house temperature. Some preferred natural air and wanted windows open, some were catching colds because of the A/C, some preferred fans. Too many opinions and disagreement about following some guidelines, such as my simple request to close windows when the A/C is on. I agree that cleanliness was an issue. I have house rules about expecting guests to clean after themselves. Some were notorious for not respecting this. This is where I may have come off as firm. I did get annoyed at some guests time after time leaving a mess for the cleaning fairies to deal with and flat out lying about it. This guest shared a bathroom with one other person. The cleaner comes once a week. Self service toilet paper is under the bathroom sink, along with cleaning supplies. Guests can watch tv after 10pm as long as they are respecting the others in the home and not disturbing anyone. Sounds like a common courtesy, right?
