Opposite Stateroom 6588 - this was our stateroom on our Western cruise in September! Wasn't really a problem most of the time in regard to smell, noise, etc. Only time it bothered me was on formal night when there was a queue for the iron and some of those waiting seemed to think it was acceptable to lean against our stateroom door even when we wanted to get in or out!
Very convenient when I wanted to do a load tho! I could just pop my head out the door to spot when a washer/dryer was available and relaxed on my verandah with a glass of wine til it was done - pity I only did one load - it was so civilised!!!!!!!!!!!!!
