Suggestions for a couple flying together?

Flying SFO-ZRH on the 77W - currently booked in 15A/15B, but I like being closer to the front and saw that 7J/7K are available. I usually fly UA/LH J so am unfamiliar with the flow on the LX 77W.

As this side is where the 2 lavs are and right at the bulkhead, is this going to be a more bothersome/malodorous location? Should we stay in 15? Thanks!
