i didn't be there finally...
the address it shows you the googlgemaps link its not correct!!!!
we arrive late time to ibiza and we were like 2 hours looking around but this place it isn't in the 1st of ramon i cajal street in ibiza.....
we think this place is in st. antonio.
Be careful because they charge me one night that i didn't spend there...
good luck!!!
