So, as with all Lisa puzzles, there are several layers and dead ends too it.
The first thing to do will be to find some kind of direction from the note, knowing Lisa this will put you on her expected (and wrong) path that will let her gloat a little bit. But if you're finding these gloats, that does mean you have found correct information from the note.
The next thing to notice is that there is some extra information that doesn't really make sense, so the goal is to find a way to make it make sense. You have 8 (if I remember correct) movements, and there are 8 greek names. But if the movements are already 'correct' from the first information, these must be on top of that, to let you re-interpret that information in another way. Given each step only has options for left, right and forward, it will have to be something to do with lefts, rights and forwards.
