In all honesty, holding your position on the high ground and waiting for the intruder to come to the stairs seems like the best options. Even in my house where my stairs aren’t as advantageous to the intruder, they are still advantageous for the intruder enough to where I won’t go down them. I would be in the prone or kneeling behind the small wall that I have pieing the corner waiting for them to come up the stairs. I do have dogs that sleep down stairs so I will know they are coming before hand and will have plenty of time to get into position. My advice would be to try to put something downstairs as a warning to let you know there is someone there.
