I do not recommend this hostel. Don't go there. My friend and I stayed there for one night and we had a very bad experience. In a few words : Poor service and terrible installation.
To begin, we arrived early, at 1 pm. The check-in written on my booking was 2 pm. There was no one at the reception to great us for 40 minutes! (The big red button and phone number didn't do anything.) When a staff member finally arrived at the counter, she said the check-in was only at 2h30 pm, which is not what my booking said. I asked if we could store the luggages while we waited for our room. She said to leave them in the lobby. We didn't want to do that so she then (and only then) asked my name and looked for my reservation. Our room was ready and early check-in was possible after all (not that early anymore).
The lack of professionalism was astounding. They complained between themselves about us to our faces in Spanish. When it became clear that we understood them, they switched topic.
Then, the building is in dire need of structural repairs. The floor is rotten in the shower room and no new pvc flooring will change the fact that the floor is giving in in certain spots. Doors to cross between buildings are only 5 feet tall. Adding to that, the curtains in our room were partially unhooked and we were too short to adjust them.
Finally, the lobby closes at 8h30 (we were told to leave). Since our room provided neither phone nor television, its a good thing we had our own entertainment.
