We spent great 3 nights in Damien's house. It was extremely clean and comfortable and almost provided everything we need (towel, kitchenware, hairdryer etc.). The staff and neighbour were super nice and helpful. There's an elevator so no worry about our luggage. One extra point is that you can use the underground parking with residence card, so we rent over-night bikes and kept them there, it was very safe. Plaza de Catalunya was within 15 mins walk and you can find everything there. Super cool experience.
