This is a lovely apartment right next to the Cathedral and on the edge of the old town, which makes exploring Barcelona super easy. It is fully equipped with everything that you need to make it your home for as long as you're there, and the team are usually pretty quick to respond if there's anything you need.
Particular highlights are the late night street singers on the right of the Cathedral, and the rooftop bar at Hotel Colom, both of which are about 2 mins away!
