Terminal 1 is frankly a modern well-designed airport with the usual features of a good international airport. The check-in was smooth was opened exactly 3hrs before boarding time. However this being the 2nd time I'm flying out of this airport I have to downgrade my rating of 7.5 to a rating of 3 for extremely poor service all round in particular by the service staff manning the Information Counters and the personnel handling the Tax Free counters. I was especially disconcerted by the way the personnel treated tourists who needed help understanding the tax free process. On both occasions when I used this service the staff were downright rude and gruff when politely asked about next steps in the process. A modern fine airport marred by unprofessional staff. My entire experience of Barcelona was affected by this last stop at the airport.
