I have a few around. When I lifted competitively (15 years ago?) we had a few Pavel guys in the community. Nice guys but... weird.
My biggest issue with kettlebells is that my basement ceiling is low so swinging them is probably out and I've only got 7 months or so of outdoor training. I'll check it out, however, can't hurt to ask.
swinging shouldn't be a problem if you are doing the russian swing (maximum shoulder height).
For the more advanced exercises military press, snatch and clean and jerk you need a room where you can stand up with your hands straight above your head.
I am training outside the whole year, but it doesn't get extremely cold here in winter -5° to -10° Celsius is pretty much the minimum. But I am under a roof and so it works for me (but I have to store the Kettlebells indoor so the handles are warm).
