February weather can be anything, but likely gray skies. More important, daylight hours are short, if it's light when you wake up, you know you've overslept! And sundown about 4-ish, so you do not want to spend lots of your daylight hours riding the Air France bus back and forth to CDG.
Lots of good 3 star hotels, you may want to check the Paris site on FlyerTalk.
