I have stayed at the ICSF numerous times and I am sure the front desk staff was indeed mortified at this mistake.
I have found their staff to be meticulous about meeting my guest requests as well as exceeding my personal high standards for guest satisfaction.
My most recent stay was the night of Aug 6 with late check-out in the 7th, which means I checked out the day this occurred.
I had nothing like this happen during my stay and my room and bedding were flawless, as was the rest of my stay.
If you wanted some compensation, you should ask at the time the incident occurs and not wait until check out.
I do not think in this instance I would ask for any kind of compensation since the staff corrected the error and I cannot see what kind of 'inconvenience' this incident caused to warrant being compensated.
I have had quite a few instances where I have asked for and received significant compensation in the form of points for grievous errors on the part of a hotel that resulted in my being greatly inconvenienced or my stay disrupted.
I have never needed to do that at the ICSF.
