Would not recommend after staying for 5 days. The rooms are very small, particularly the bathroom where you can hardly squeeze in. Walls are thin and noise can be a problem. The floors and walls were old and dusty. There are much better 2 star hotels in barcelona city centre for a cheaper price (from personal experience).
After staying here for 5 days, we moved to ANK (a hotel 2 blocks away costing the same price with breakfast included), where the conditions were amazing in comparison.
If you are desperate for a cheap room in barcelona and are having trouble, then I would recommend even considering Air BNB as a better alternative.
