My sister-in-law has a bichon frise. She's a lovely dog. They do have a bit of a stubborn independent streak, but I find that quite endearing - SIL's dog happily decides what she wants to do, then goes ahead and does it. So careful training is needed to ensure that what the dog wants to do lines up with you want to her to do (which is the secret to all dog training really). This isn't something that should put you off the breed at all, just something to be aware of. I think they also have a tendency to bark whenever someone comes to the house, even if it's a member of the family!
