Alex is an excellent host. He welcomed us with very good cava from Catalunya an a "all you need to know" kit that he has prepared and keeps upated. The place has many advantages: location, beautiful and clean. It's a stone throw from la Sagrada Familia so you would have an advantage over others to arrive early and avoid long queues. There are two metro lines jut around the corner and a bus that takes you directly to Plaza Catalunya and Montjuic. I fully recommend this place
