Cabin #323 on Promenade deck, oceanview on the starboard side. Great location as we were able to be outside within minutes on covered deck with walking facilities. Very convenient to the shows, dining room, and everything onboard. Great closet space, loved the bathtub.
Only downside...other people went out every morning and got the deck chairs right outside our window. so if that would bother you, look elsewhere. No chairs were placed on the port side since the rail was solid and the view was more limited, but still provided more privacy if that is an issue. Read entire member review.
As I noted in my review, the Maasdam cabins have a air vent which is about 8"x 11" and it allows ALOT of noise from the corridors. I didn't see them on other S Class ships. I've already told HAL that cabin 388 is far too close to the elevators to be considered at C class cabin. You could hear elevator bells each time arrived a deck 6 (lower promenade deck.

Our cabin # was 391 I think we were below the galley because around 11PM we could hear tables & chairs or something being pushed across the floor. This didn't bother our sleep because we were up late-reading for just coming back to our cabin. If people turn in early I can see where it would be annoying or could even wake you from you sleep.
Adequate, but lacked mini fridge. Rented one for $2 per day. Good location, near atrium, elevators, stairs, but not noisy. Window looked out on promenade. OK during day, since we could look out but walkers could not see in. At night, with our lights on, it was possible to see in, so we had to be careful to keep curtains closed. Comfortable and adequate, but nothing special. Read entire member review.
