This is a great hotel to stay at if you have an early morning flight. It is literally a 5 minute cab ride from the airport - and the cabs were already lined up outside the hotel at 4:45 when we left. Better than waiting for an airport hotel shuttle bus. About 10 minutes from a commuter rail station that will take you into the center of Barcelona for 95 cents assuming you have bought your Metro tickets at the 10 for 9.50 Euro price (the commuter rail takes Metro tickets.) Also, the 10 for 9.50 Euro tickets give a free transfer to the Metro - while the pay by the single ride tickets do not give the free transfer.
If you are coming by car, there is lots of free street parking.
