This review is for the private double room with private bathroom. They don't have a front desk, so we had to meet up with somebody from the hostel in front of Hard Rock Cafe in La Rambla, which was not a big deal since it was close to the hostel.
The location is excellent as it is right by La Rambla, a busy street where everything was happening. The hostel was also within walking distance to the bus stop for the airport bus, which was super convenient.
The double room size was pretty big in my opinion. We came in October, so the lack of air conditioning was no problem for us as it was cool enough at night.
A couple things that I thought were inconveniences were the private bathroom & the lack of luggage locker. The private bathroom was located outside of our room, but it has a lock. So, we had to come out, unlock and re-lock the bathroom every time we wanted to use it. Furthermore, since there's no luggage locker inside, we had to store our luggage in an outside locker (which was still within walking distance). Not a big deal, just a bit inconvenient.
Overall, we were satisfied with our stay there. It was a cheap hostel with an excellent location. We would definitely stay there again.
