By the time Barcelona rolled around I was mostly burnt out.  It didn’t help matters that my first night spent in the hostel there was interrupted at 3 AM by two people having EXTREMELY LOUD SEX.  

Something very important to remember.  If you can book a co-ed room in a hostel I def recommend it. If for instance someone is listening to music or talking on the phone, you can count on the dudes in the room to yell at them.
When I was in Barcelona I stayed in an all girls room, 16 beds.  Although the loud sex woke everyone up NO ONE except me told them to shut up.  They didn’t shut up anyways.  
I still get angry when I think about it.  Drunk people who are also inconsiderate are the WORST.
Anyways! I laid around a lot in Barcelona but managed to drag myself out of bed for a walking tour which was really awesome.  Every bit as good as the Amsterdam walking tour.
(I love walking tours)

 Old school Gothic architecture!

 Where Picasso studied.  Also the heart of the red light district.
