Perhaps getting rid of height limits entirely isn't a great idea, but an overall height limit that allows building up to one story taller than the buildings next to the one you are building seems reasonable and would allow a city to grow up gradually. As far as desirability--what makes European cities desirable and charming? I'm certain it is NOT ample parking or one story bungalows with huge yards.
