Well, sweet_fallacy above mentioned preferring a female to share a bed with, and you and I have friends in common, so you seem vouched-for. I should ask if the entering and exiting (presuming you'd be considerate and quiet about it) would bother her. Also, given your occasional daytime naps, would the Sunday afternoon room-taking-over be a problem for you? Would you be looking for all three nights?
This might be a workable situation.
