"She was a nice person" in spanish is "ella era una persona amable".
It depends on how "nice eye" is intended. If you are referring to the expression indicating that a person is very perceptive and notices minor details, the expression in Spanish is "De buen ojo" If you are merely trying to say that an eye has a nice shape or that it's pretty, you can say "ojo lindo".
Son muy amables means "They are very nice" in Spanish.
