I was impressed by it - its sheer size and the overall idea of one large city-planet, but by NO means would I like to live there! (visit it , maybe, but no living!!!) I find the natural world spectacular and relaxing - I preffer a combination of state-of-the-art home and nature, to be precise.
But, yes Coruscant is spectacular - especially when viewed from above or outer-space, where one can observe the two hemispheres, the dark one bearing the intricate patterns of the illumination far below.
