Sleep between 2000 year old walls in Barcelona

Christmas was spent back home but, as usual, over a very short and packed 6-day trip including two way 14h flights. 

Because we had very little and I wanted to show Sam everything there was to Barcelona in only 4 days, cut short because of the multiple Christmas holidays, I had prepared an itinerary with tourist sights and activities as well as good food, the best way to experience the Catalan way of life.
