Great accommodation and host, in a really great spot. We used it as a base for work, as it was cheaper and more independent that 3 of us getting separate hotels. The rooms were all good sizes, one was en-suite, ideal for 3 of us working on Avenida Diagonal (about 2 miles further up).
I would say that the street can be a bit noisy on occasion, and there are also no curtains on that side, but it is a great space inside including a huge space outside with Chairs and Tables - so it would suit larger groups probably 2-3x couples or 3 beds for people working in the city/locale.
Great links up and down Diagonal, and an easy 15 min walk to the La Sagrada Familia, and loads of Pubs, Cafes, restaurants in every direction from the property
Host was excellent on communications, overall a great stay - thank you Paco
