Hi Don, I'm sorry you were disappointed in your experience. This is clearly a first as the other reviews (including the cleanliness rating) indicate.
Since this is a public forum, I do feel it's appropriate that I tell the host side of the story for the benefit of future guests:
As you know I usually free my schedule to welcome guests personally and make sure they have everything they need to make their stay enjoyable. Now since you arrived very late, I could not make that happen this time around
You texted me the day after that the sheets were dirty, which seemed very odd, as you were the first time users -but you never know. I apologized and made sure I came by at your earliest convenience. I inspected the sheet which indeed was completely clean. I added a clean top sheet (which was what I thought you required, as the bed admittedly only had a comforter) and asked if you wanted me to still change the bottom one. You said that wasn't necessary. I assumed the matter was then settled.
You did find other sheets in the closet, but in all fairness, had I been able to give you a tour I would have politely asked you to keep out of those closets as they contain some personal items (including previous sheets that I did not have a chance to clean yet).
All in all, i'm convinced that better communication could have prevented this mishap and feel it's fair to state that guests indeed can expect clean sheets in a comfy bed as well as the other amenities advertised in the listing!
