To be honest I hate that seat since the lights from the lavatory and people moving in and out all the time are really disturbing. I even had the middle seat free and was thinking: why the hell did you pay money for this crappy seat?

On the way back a isle seat (also free middle seat) in the first Eco section was much better in my opinion.

But I'm not that large (1,75m), slim and used to suffer long trips in LH economy
