In my opinion, you can't expect to get a 5 stars hotel when you are paying very little. This hotel is not the best place I've ever stayed but it wasn't THAT bad as other people make it sound either.
The AC issue, it works but you have to request the remote control and I believe they charge you a couple of Euros. This hotel, is actually self catering apartment style, so no, you won't have someone changing your towels every single day and making your bed. And no, you wont find a mint on your pillow.
This is a great place if you come to Ibiza to party, we're a couple in our late 20's and stayed there twice. Once in 2009 and another time in 2011, the front desk were very friendly and yeah, they're English was lacking but this is Spain after all.
Below (as by the hotel pool) you'll find a hot spot for the evenings, Buddha bar. When we first one in 2009 it was low key quite place, after some renovations by 2011 it became a hot spot in Plaja D'en Bossa. The pool is nice and clean and the front desk very friendly, their only "fault" might be not be 100% fluent in English but they try hard to make themselves clear and to understand you. Also, this hotel is right next to the famous Bora Bora and walking distance to Space, Usuahaia (overrated place, but that's another issue) and tons of bars. The beach is great and the people beautiful.
We would definitely go back there to Tur Palas :) Enjoy!
