When checking-in online I'd seen that there were suddenly plenty of free seats upstairs which surprised me (having only ever known full flights in Premium) and I was lucky to have an empty seat next to me. Having suffered from the excessive volume of the pre-take-off music on my flight 4 days earlier I was a little shocked to hear the same few songs, yet again being played loudly and this time I asked if it could be turned down a little. (And I'm a musician who's spent much of my life in the studio!). Apart from that it was all very comfortable and easy. I even slept a little. The crew were professional and courteous. No complaints at all.
