Aside from both being old, Rome was HOT. Paris was chilly. All the sights in Rome were within easy walking distance of each other. In Paris we had to take a freaking bus everywhere because it was so much more spread out.
To the tourist, Rome felt disorganized, with crumbling ruins right in the midst of a modern city. In Paris, you got the sense that everything was very neat and clean.
& I loved it all. I couldn't possibly choose between the two. Rome was so spectacular, so impressive, and so humbling. Paris was GORGEOUS and the weather was perfect for sight seeing.
I make no apologies for the amount of pictures in this post. Also, our hotel was 5 minutes from the Eiffel Tower... hence the many pictures of it.
