Love Hina I'd say. If you want cute girls then search for harem anime, it's the genre that better fits that expectation. Outside the harem genre I'd say Silent Möbius or Vandread. You can search by theme in Anime News Network; beware that in older anime (before 2000 specially) the characters might be well drawn one chapter and then completely wrong drawn in the next one. Also, normally OVA has better animation because of it's budget.
