I have been to Paris twice and on both ocassions i have returned to the Eiffel Tower! I absolutely love it, and considering how much it is to ride the London Eye i think the entry fee is really rather reasonable! You can access all floors of the tower and the view from each floor gets better the further up you go. A 360 degree view of the city of love and its nothing short of breathtaking! I am going back this summer with my boyfriend and i can assure you i shall be, once again, visiting the Eiffel Tower. Yes, the queues are quite big but they go down rather fast and your on your way up to the first floor before you know it! Theres a restaurant on the first floor which is absolutely gorgeous to eat in overlooking the sights of the city, especially at night when everything is lit up. I have been to many cities of the world and visited many attractions but this is definately up there as my favourite!
