I stayed with my friend in a twin room with a private bathroom and in general this was a clean and comfortable accommodation. It is close to the main attractions - it took us 15-20min to La Bouqeria market and La Rambla, 20min to the Gothic quarter and around 15min to the Montjuic neighbourhood (La Sagrada familia would be around 40mins by foot). If you don't enjoy a lot of walking, this place is well connected to all the other parts of the city with public transport and taxis that pass by often. There is someone at the reception at almost all times, so you can ask for help or assistance if needed. You can expect to get towels, soap, shampoo and toilet paper, so you wouldn't have to worry about that. Also, the super market, pharmacy, some small cafes and fast food chains are really close by (5min walk). On the other hand, you can expect slightly more noise than usual because the walls are very thin and the rooms are right next to each other, so you won't have complete silence (but this didn't bother us that much). Also, people we met in this hostel are not that fluent in English, so the communication isn't always clear and it would help you if you knew even a little bit of Spanish (at least to understand them). All in all, this was a good place for the price we paid with no major red flags and I would recommend it.
