my husband and i stayed there for 4 nights in august 2011. to be honnest, i was very worried being that we had never stayed in a hostel before (never less than a 3 star hotel), but ibiza is such an expensive island, that we had no choice but to try a hostel.
i had reserved a room with AC and that was a must being that it was 40 degrees every day.
location: in a quiet street in San antoni. near all the craziness but far enough to be able to sleep and not hear the noise from outside. 10 minute walk to the san antoni bus station, with is a big advantage to visit the rest of the island. Good for someone that want to stay in San antoni (if i had to do it again, i would stay in ibiza town...to many young and loud germans there)
rooms: room was ok. i guess we had the best room in the place as i saw other rooms and they were tiny. room was clean, but very old looking. the worst part was the bathroom as the shower curtain looked old and stained as well as the towels (i used my own that i had brought). the room size was pretty good and we had more than enough room for all of our things.
Beds were not very comfortable but ok to sleep on.
staff: that was the best thing of the place. the staff was amazing...always there to help and the answer all of your questions with a smile.
all together, and for the price we paid it was a good place in san antoni.
