First place I ever stayed in Ibiza - they are right about the stairs. We went on a really cheap 100 squid deal with 18-30's so I went fully expecting the worst.
The rooms are actually nice, they have their own bathrooms and kitchens etc. The balconies are rather small but if you are gong 2-3 of you, it will be ok, There were 3 of us and we thought it was fine. Rooms are small, basic but bright and there is a snack bar and pool downstairs which are all ok. Not to far from West End and Cafe del Mar but enough out of the noise. I reall enjoyed my stay there.
Have Fun x
