Aus Traveller is right - The photos are of two separate areas in corners of the wall and sliding door along the balcony, hidden by the curtains. My husband was looking for power outlets to connect our C-Pap sleeping machines. As we have health issues, good quality air is crucial. The filthy areas were reported to head of Housekeeping. It took 3 hours to resolve relocating us from midship to stern and getting to bed at 12.30am. Housekeeping had no further contact or follow up. Accidents can happen, but this had been there a long time. In COVID times when cleanliness is promoted by a Company, this is not good enough. We have done 15 prior cruises and never experienced something like this.
