Cliche but pretty
Paris was very beautiful but its also the cliche of romance and all the couples on vacation/honeymoon. To move around you have to use the metro. Paris is veeeery expensive so watch how you spend.
Insider Tip:Buy souvenirs from the guys who sell around the Eiffel Tower. Those are the cheapest and you can also ask for a deal. Buy a bunch of baguettes and make sandiwiches to take with you. Its easy and really cheap.
