Many, many forms of training will be effective in some way.
A more useful question to ask is, "What training methods make the best use of my time?".
A height-adjustable floor-to ceiling ball (even if the ball is just a tennis ball, which you can make yourself very cheaply) will still train muscular endurance, with the important added benefits of improving reflexes, timing, and - if used properly - technique.
It's important to note that a floor-to ceiling ball can reinforce poor technique if you are a beginner. That being said, it is an excellent tool for the home for the following reasons:
It won't annoy other members of the home and/or neighbours nearly as much (it is much quieter, especially in the case of a tennis ball), meaning you can spend more time training.
All it requires is a small hook in the ceiling and a moveable weight anchor at floor level, so you can dismantle it and erect it easily, any time.
