A friend and I stayed here for three nights, and it was delightful. Our room was clean, modern, and well air-conditioned. The location was ideal, as we both like to sleep (even if we start at 5am, as is the culture on the island) and Talamanca, while close to Ibiza Town, is fairly quiet at "night". The concierges were courteous and very helpful. We were only awake for breakfast on the final day, but it was very good (and free with our booking).
The only downside was the elevator - it wasn't very fast - but I prefer the stairs, anyway.
