I had 8H recently JFK-LHR and didn't care for it all that much. The legroom was fine but I did not like looking into the F galley all night. They never turned the lights all the way down and the light was distracting. I noticed that there is a curtain up there but it was never drawn. On the plus side, service is much quicker up there than in the main C cabin, which is nice when the flight is short and you'd like to rest.
