Great info W-T-P!
Have a great time in Barcelona - I recommend to checkout the Basílica de la Sagrada Familia; also known as the Sagrada Família, it is is an incredible large unfinished Roman Catholic church Designed by Visionary Catalan architect Antoni Gaudí... it is truly amazing! Climb the stairs of the various spires to get a breathtaking bird's eye views of the city.

Upvoted and resteemed :D
