So you see, Lisa, that you will get different answers, and that's healthy too. I like Eric's, as he is probably asking you to be simple, practical; be like a child.
In a general way, many of us refer to Heaven as a place of beauty, Light, Love, Happiness, Serenity .... you get my drift.
My own view is that the spiritual life is a mystical one, and that Heaven and Hell are states of Consciousness/Spirit. When we are well-intentioned, loving, simple and pure, we are moving towards Heaven. When we are dark, resentful, burdensome and full of hate, then we are moving towards Hell.
They are actually finer inner realms. The angels live there, and those pure Souls too, but we are on a much grosser, denser plane, and that's why we have to do spiritual practices to encourage receptivity in our being. Gradually, we learn how to go to this beautiful realm, or plane of Consciousness. Much Love.
