To begin, you should not read into the bad reviews too much. This is a new hotel, clearly there will be some teething problems such. I however had no problems at all, stayed in a Silver room on the 6th floor 1628 - great views of the beach. I would ask for a room on the pool/stage side if you don't like music til late as Ushuaia play music quite loud. On the side that I stayed however, you could hear the whole of the Guetta show at Ushuaia, I went to the show and watched/heard the last few songs from my balcony.
Room very good, great black out blinds and air con. Mini bar has space for your own things. Huge shower and great mirror/sink area. You also have a great docking system for iPhone/android and it also has Bluetooth for other devices. Wifi incredibly fast throughout the hotel, even by the pool.
I had room service three times while at the hotel, great quality food however it is pricey but this can be expected of a 5* hotel and in Ibiza.
Poolside service very slow, ordered food and drinks at lunch and the drinks arrived after the food! Quality of food again very good.
Would definitely stay again.More
