Just wanted to add that I totally understand the point of housekeeping being able to "miss" these types of issues. If I understand correctly, someone must review/approve the room for release after it's been cleaned. To have someone in charge approve this type of room truly needs to be addressed from the top down. There was no way your room (or the rooms we had in September) should have been released for guest usage. This is so unacceptable.
To the OP, I'm not sure what room you had but I think I read you were in Congress Park? We stayed over Labor Day weekend in a 2 bedroom in CP. The studio portion smelled like a musty old pirate ship. The smell of mildew & must was so strong coming from the studio portion that I did not allow our teens to sleep there the first night. The AC would not work. It would not cool the room at all (probably attributing to the smell of mildew & must). We weren't able to shower in the bathroom of the studio as the stopper to pull up (to make the shower head work) was stuck. It wouldn't pull up. Maintenance told us it would be fixed "after" we checked out as it would require an entire new fixture.
We had several people from maintenance there over the weekend. I talked to the head of HK and the GM. They cleaned the AC, changed the filter, put a maintenance request in to fix the shower, sprayed repeatedly to get rid of the smell...all to no avail. The AC never did work right. We were only there 2 nights and the 2nd night they moved my teens to a studio across the hall. I can understand the shower portion being missed but there is no way anyone could miss a hot, smelly room. Especially since as soon as you entered the 1 bedroom portion the difference was so obvious.
The part that bothered me the most was that someone in charge would approve a room like that to give to another guest. We tried and tried to make sure things were corrected before we left. Even mentioned it again at the front desk when we checked out.
I don't remember the issues you had being part of our issues, so I am assuming yours was a different set of rooms at Congress Park. Maybe that whole section of SSR needs to be closed for a major rehab.
Hoping your next trip will be better.
