I have an 8 am train from Barcelona Sants to Atocha Madrid. I am renting an apartment two blocks away from Plaza Espanaya. My wife and I each have 1 pretty good sized suitcase and 1 carry-on bag each. Obviously we will need a taxi to go from our apartment to Sants. What is the most comprehensive way to accomplish this task? I do not have a European cell phone and do not have a phone in the apartment. I do have a Netbook with Skype capability which would allow me to make a telephone call. Help.
