Guess where!

I have also been enjoying some days off and following João's post, I've made a photo collage with 4 pics of the one thousand we took :)
The question is... where was I???
Other questions come up, though: How do you know? What info can you add about the place I've been to? Have you ever been there?
Below you have the collage but to listen and see what I've drawn, you'll have to click on the link below . Do listen and enjoy; I'll be waiting for your answers:

PS: Some time ago, I challenged you here to use Vine and those who had compatible Android versions shared their creative Vines here and here; why don't you try now Clarisketch, this free Android app?
