On a bit of a whim I have booked flights for us to Barcelona. We are there for four nights at Easter. We want to see the Gaudi sights and my dh says we need to go the football stadium. What else do we need to see? Can someone suggest a good area for us to stay in. I'm thinking of booking an apartment. A friend has suggested we stay in Sitges and get the train into the city. What do you think?
