Could not be a better location. took the Aerobús from the airport which was only 6 euro and really easy. A very short walk brought us to Concha's door. Her place is in the middle of everything. She met us at the door and gave us the tour to her compact apartment just as described. There are Fantastic restaurants and tapas bars on her block. We walked to the sea and also to Sagrada Familia along gorgeous old narrow and twisty streets (GPS was pretty handy). Barcelona is a beautiful city and I hope to come back sometime.
