Enjoy BCN, it will be the perfect city in which to do your break. And given the various influences on the city from the cultures of the mediterranean, an ideal bridge between Israel and Turkey. Check out the new Museum of the History of Catalonia by the Old Port, and just gawk at the wild architecture all over town! The only problem with BCN is how full the hotels can get, particularly on the weekends, and how expensive most are. Getting to and from BCN airport to most points in town is also easier than in MAD.
