I believe there is no right or wrong answer to that question. A memorable image can be made with whatever location is chosen. That's not to say the location doesn't influence the image but it's not the most important part of the photo - you are.
Let's take a look at some examples.
The photo above was taken in downtown Raleigh. Now, you may not have known the location but I suspect you would have guessed it was a city. That's because the are no trees, flowers, or grass in view. Instead, you see a metal chair, cement, and reflective glass.
Notice, though, that the location is not the main focus of the image.
The image above demonstrates a different choice. Once again though, the location is not the subject but notice how it influences the image. The reflection of the trees, the serenity of the water, and the green grass provides a calming sense to the image that the city image might not possess.
So, when it comes time to choosing a location for your photo session, think about the feel you would like your images to have and understand that you are the subject, not the location.
