I had a Rolleicord V for about a year. It's REALLY sharp and easy to use.
It's a simple camera.
Focus, set exposure, click. Wind, and repeat.
This of course assumes you are familiar with manually focusing lenses, know how to set shutter speed and aperture. If your prior experience is a modern camera with everything automated, I guess it'll be hard but it's not anything that's daunting even if that is the case. If you can use Pentax from 60s, you'll have no issues with any of this, I think.
You'll want a light meter though.
