The Stratford, Autograph Collection in London

My stay started off reasonably well, but the second night turned into a very frustrating experience.
After my first night (booked via Marriott APP), I decided to extend my stay via Trip.com (which resulted in being assigned a different room), as overall the hotel seemed acceptable, though there were some minor issues in the room — for example, the faucet was loose, and the toilet made noise when sitting on it (to the point where I was slightly concerned it might not be properly secured). Breakfast was à la carte and tasted decent.
However, the second night was extremely unpleasant.
When I was about to go to sleep, I noticed black marks/stains on the bed sheets, which made me uncomfortable. I called the front desk, and was told that housekeeping had already finished for the day, so there was no one available to change the bedding and no immediate solution offered.
When I asked what could be done, I was told that clean sheets could be brought to me — which implied that I would have to change them myself. Only after I questioned this did the staff offer to move me to another room.
Shortly after, the staff came to my room and informed me that I would need to pack all my belongings and move to another room on a different floor immediately. I was also told that I could not leave my belongings in the original room. As she was the only staff member on duty, I had to handle all packing and moving myself.
This happened at around 2:00 AM.
I was genuinely shocked. Based on my past experiences with Marriott International hotels, the usual approach in such situations is to allow the guest to move to a new room to rest first, and pack belongings the next morning — especially at such a late hour.
What concerned me most was not just the inconvenience, but the response. When I tried to explain why this arrangement was unreasonable, the staff focused solely on the fact that she was the only person on duty, rather than acknowledging the impact on the guest.
The following morning at checkout, I raised this issue with the front desk. I received a rather expressionless apology, along with an explanation that she belive it was a “miscommunication.” This response felt dismissive and failed to address the core problem.
Obviously, there are issues in:
• Hotel management (only one staff member on duty overnight)
• Service policies (no proper solution when basic room issues occur)
• Staff training (lack of customer-oriented problem handling)
