While there may be a taste issue, the water provided in Ibiza is safe to drink. There is salt and calcium content in the water provided, but as long as your stay is short the water won’t have an unhealthy affect on your body. You should probably bring a filter that could remove calcium and salt or be prepared to spend money on bottle water for extended stays.
