[Paddlewise] Backyard pool for kayaker?

Anyone have any tips for choosing a backyard pool suitable for rolling
practice? Other than size, is there anything else to consider? Are steps
leading down into the water any easier for getting in and out of the
boat? I saw a picture of a pool that had a "beach entry" (gradual
slope). Would this be worth considering? Any advice appreciated.

Thanks,
Frank
