Carles,
Is a superhost and great with communication and accomodations to everything you need. His Airbnb is located in a phenomenal area within Barcelona near anything you may need to see or pickup. The unit itself was designed by Gaudí and layout alone is just amazing to checkout and visit. I highly recommend checking out especially if it's your first visit in Barcelona like it was mine. Hands down best place I ever stayed at if you get the chance I would say just do it !
Muchos gracias para todo Carles.
