For anyone staying at the NH Calderon interested in a simple and affordable option for ground transport from BCN (El Prat), may I suggest the following: the Aerobus A1 route will take you from the baggage claim level in front of any of the BCN terminals directly to Plaza Catalunya in 4 stops. A rudimentary bus route map can be found here: http://www.emt-amb.com/links/lineas/tcc/aero.htm

The bus runs every 15 minutes with en route stops at Plaza Espana, Av. Gran via de Corts Catalanes, Plaza Universitat and then Plaza Catalunya. When you get off the bus, you will be on the east side of Plaza Catalunya; to get to the NH Calderon, walk up that very street (Passeig de Gracia, heading north, with the one-way traffic flow), crossing Gran via de les Corts Catalanes (a major divided east-west boulevard); the NH Calderon will be at the end of next block on the southeast corner of Rambla Catalunya and Carrer de la Diputacio. The Aerobus fare is 3euro30 one way, 5euro65 return. A taxi will run in the neighborhood of 25 euros each way.

Hope this helps - sorry about the verbose nature of the directions, I just assume if you haven't been there, & you're like me, you like your directions on the detailed side. SeeYa, good find on that 110 euro rate, I got that snagged today...another 38 euros to party with!
