I must say this was spectacular. The early days are much nicer as the flowers fade and the colors are not so vibrant after the first two days or so.
We paid 5 euros to get up a balcony to see the flower carpet from higher grounds. There isn't much to see in the building itself. The crowd is definitely going to be massive so it's a little uncomfortable to be up in that relatively narrow balcony trying to snap a few good pictures along with everyone else. There is a stairways to get up and strollers and other wider objects will definitely be challenging.
