Buy tickets on your phone, save 2 hours. Ensure you pick the right time to arrive (start the tour) when you buy the tickets. It is not a tour, just a way to get in and walk around. If you do not buy your own tickets on the phone, then buy them at the tourist office, no line in the city, it is a few blocks away. Take water bottle, very nice waling shoes, it is ALOT OF WALKING. Buy the Macaroons, they are costly, but the best in the world there. Read up before you go, and buy a picture catalog for about10 Euro, they take better pictures and you can enjoy the vista instead of being annoying holding your phone bumping into people.....just saying =-) Kidding....enjoy yourself...beautiful and full of history.
