Building out Bedrooms in a 7 - 8 Foot Basement. Is It Comfortable?

My family is looking at a South Slope two-family, wood-framed home. It’s currently setup with two, one-bedroom units with 9 foot ceilings. There’s also an unfinished basement with 7 – 8 foot ceilings. We’re exploring finishing the basement, ideally adding two more bedrooms and a bathroom (this would make the bottom unit 3b/2ba). We’re not very tall, but don’t want to go through the work to find that it’s too unpleasant a place to live. Anyone do this and live on a short ceiling floor? Is it comfortable?
