Al is the amazing host! The communication was great. You can rely on him in any situation. The apartment was super sweet and comfortable, it has everything that you need except shampoo and shower gel =) This is a room in 3 room apartment, 1 room for guests and 1 room for very good and nice man who lives here constantly, but he is almost invisible. The apartment is close to the Gothic Quarter, La Ramba and Montjuïc Park. There are a lot of restaurants and supermarkets in the neighborhood. Also, there is a quite noisy restaurant, right under your window, especially on Friday's and Saturday's nights.
Also, the district looks like there a lot of people who moved to Barcelona from other countries. But it's totally safe. Also, I think that price is a bit high for such type of accommodation, but this is a common for Barcelona.
