I used to think that about the fluids too, but it's not the case. You'd experience some swelling, perhaps up to twice your normal size, but the tissues are elastic enough to keep from bursting. But all the fluids in the body are under pressure already, simply from tissues and membranes, thus while the temperature at which blood and other fluids boil is reduced, it remains above 37 degrees C. You can expect your saliva and tears to boil off, which is surely an interesting sensation.
We've demonstrated it on animals, which show that complete recovery is normal for exposures shorter than 90 seconds, much longer if breathing is not impaired. The only human examples are brief and non-fatal accidents, and one of a series of human experiments for the Luftwaffe on prisoners at Dachau camp in 1942.
Rapid decompression can cause physical trauma.
Other exposure dangers in space include radiation and dust particles, which travel at very high speed. Cold isn't much of a problem: most heat loss of earth occurs from conduction, which is... rather limited in a vacuum. Only heat radiation is an issue, a long-term one.

What are the best conditions in space supposed to be? Slightly less freezing cold? Not quite as vacuum-y?

the best place in space to be is definitely the surface of planet Earth, though I'd be very choosy about my precise location. Lots of places to be that are as inhospitable as the vacuum of space.
