Any feedback on suites 636 or 638 on O class ships ?

I'm looking at a cruise that's currently almost sold out.

My preferred location for this one is midship deck 6. The only available suites are either 636 or 638. Those are either side of the crew service stairwell.

I'm noise sensitive and I'm concerned that those suites may be noisy due to crew activity.

Not those exact suites but was in 641 (opposite) for 14 days and was perfect. Did not notice any staff traffic.

We were in 636 on Quest a couple of years ago with no problems. I am also noise sensitive and a light sleeper.

Thank you both for your replies. By the time I got back to my TA on this one the cruise had sold out - my bad as he did offer to put one of the suites on hold for me for a few days whilst I made up my mind.

Hopefully the information may be helpful to someone in the future if they're searching the board for similar feedback about either of these two suites.
