At first glance the accommodation is super basic and aesthetically unpleasing BUT I stayed here for more than a week. The accommodation is good value for money, the staff is super helpful and friendly, the beds perfect and the shower perfect with very good water presure. Fridge, microwave, iron and kettle are available on request. Bring own coffee for your room. The acc is near Lesseps station and in walking distance from Parc Guell. There are other areas that have nicer open public spaces and outdoor cafes. The one plus point is that there is a no noise rule from 23h00 to07h00 so that really adds to a sense of tranquility.

You can tell the quality of a place for the helpfulness of the staff. The hotel cares more about profit than the quality of the stay of its guests.
Please keep reading for some background information about my comments. I booked the hotel via a booking website and from past experiences I usually book non refundable rooms. This time I was very unfortunate to having to change my bookings because of Covid. The hotel didn't want to change my original booking and I had to get in touch with the Booking website to make it possible.
My passport was about to expire in three months so I was uncertain when I could rebook my hotel for, but given that I only have a couple of days to do it, I contacted the embassy to get an appointment and asked how long it would take to get a new passport. The embassy told me it would be 4 weeks from my appointment so I rebook the hotel for 8 weeks after my appointment just in case.
The day of my booking was coming but I still had no passport, I contacted the embassy and they told me there have been delays and I wouldn’t get my passport for 4 months. I tried to change my hotel booking once more but the hotel did not want to do it. When I contacted the booking website (with different staff this time) they couldn’t help me either so I lost the money I paid for the booking.
I take responsibility for my mistake of booking a non refundable room but I did not want my money back, I just wanted to change the date. I did not expect my passport not to be ready, it was out of my hands and I could not physically go. It would have not cost anything to the hotel to change the date but instead they just wanted to take my payment despite my misfortune.

Staying one night only in Barcelona, this hostel was a great find. On coming in, the staff were very friendly and welcoming, answering all our questions and helping us get grounded in the city. Our room was simple but clean, with everything we could need. The bathroom was lovely, great temperature, and the balcony a wonderful thing to have (the parakeets outside not so much, but that's not something that the staff can help!). Breakfast was okay in the morning, but the value and the location couldn't be beaten. The only downside was that my bed kept moving along the floor when I lent against the back wall - slightly annoying, but nothing major.
