Oceana C Deck

We've just had our saver inside cabin allocated. It's C620, mid aft. It's got white space next to it in brochure deck plan. Anyone been in or near this cabin? Is it OK? Thanks.

We were in the opposite cabin with balcony, we liked the position, it was very quiet and it was near to rear lifts, which we didn't hear any noise from. We booked the same cabin for our next cruise a year later. The white area is for the staff, either stairs and storage or both.
