When I went in 2006, I didn't personally stay there but the majority of the group did so I spent quite a lot of time there and thought it was an absolutely fantasic hotel. I can't really comment on if it's noisy at night but none of my friends who stayed there said it was but who goes to Ibiza to get early nights and plenty of sleep anyway? If your a young group of boys or girls this is the hotel for you. The hotel was clean and the facilities were excellant. It's in a fantasic location, right next to the West End and sunset strip but also tucked away in the back streets so it doesnt get too noisy. I'm going to Ibiza this year and I am staying at the Ibiza Rocks Hotel and I cant wait. If your staying in San An I really dont think theres a better hotel. Highly recommended.
