What does acceleration in deep space feel like?

Humans can supposedly sense acceleration. So what would piloting a spaceship in deep space feel like? General confusion about relativity inside.

Presumably a spacecraft would accelerate by throwing mass in the opposite direction. Without a large source of gravity nearby, would you be able to feel that acceleration inside the ship? I would assume so, but how does that play into the concept of relative motion? Wouldn't you only be accelerating relative to whatever you threw in the opposite direction? If so, couldn't anything else floating through space act as a frame of reference?
