Just wanted to say, having returned from Capri today, this description was absolutely fantastic. I'd screen-shotted your descriptions and used them to find my way up. The steps up from Marina Grande were by far the toughest bit of it, the path from Anacapri onwards was fairly easy (in my opinion).
The walk was superb. Felt pretty smug at the top, absolutely everyone else had taken the chairlift up.
Taking the chairlift down for free was also a great shout
Thank you so much for your info!! Much appreciated.
