I`m a hot sleeper as well, but you'll find that ambient temperature has a profound impact. I actually sleep more soundly with a sheet + (very) light comforter at about 17 degrees celsius or lower, having read that cool temperatures such as those are best conducive to quality sleep.. this is only true with adequate bedding, though that detail is often omitted. In the summer, without AC, I can only sleep with a single sheet barely covering me. But the quality of sleep is noticeably lacking unless I'm particularly lucky. This is because, in environments that aren't super-well climatized like modern high-rise condos, temperature may swing and fluctuate a lot, so reaching thermoneutrality (the correct amount of covering on you) can be difficult, particularly with just a sheet in my experience.
