Question: What should I do for banking in Ibiza?
Answer: Firstly I kind of need to know what services you require from a bank. If it'd just to withdraw funds you have saved in England then what myself and all of my friends do is just use their english bank account. I you factor in the costs of transferring money from an English to Spanish bank account then the cost of just withdrawing from an English account is just minimal. If you bank with Santander in the UK then you can withdraw funds for free from your british account at the Santander bank at the bottom o the West End in San An. Most jobs in Ibiza will pay you cash, so realistically you won't need a spanish account to get paid from your job. Again if you plan on saving money whilst you are there then most people tend to just save cash, and if you get a sizeable amount send it home with a trusted friend or family member who visits. Good luck saving money in Ibiza anyway. In terms of any money I've ever saved, I've always given it to a trusted friend, such as my boss who has a safe, to look after. I did read on here that one of the banks allows you to open an account without an NIE...but tbh everyone I know in Ibiza, Including those who live there all year round, don't have a bank account. Maybe all my friends are just crazy paupers though, who knows. I you really want to open a spanish bank account, I'm sure one of the all year round residents will be able to advise on this.
Question: What do I do about Health Care?
Answer: I'm assuming here that you are British. IT IS AN ABSOLUTE MUST THAT YOU GET THE EUROPEAN HEALTH INSURANCE CARD (EHIC) BEFORE YOU GO. Previously called the E1-11 it means that the NHS will cover you for emergency medical care in another european country. A good example of this is last year both myself (British) and an Australian friend got admitted to hospital will heart problems within a few days of each other. I got completely free treatment on showing them my card. She got a bill of over 2000 euros. Secondly, get travel insurance to cover you for the whole period. YOu will be able to get a good level of cover or 4 months for around £50. This is important because if you get hurt and need flying back to the UK, or god forbid, die and your parents want your body back the EHIC will not cover you. Also important to note that travel insurance doesn't cover you if you are drunk or on drugs, the EHIC does for emergency care. So they work perfectly hand in hand. The EHIC is also useful i you get something simple like an infection that needs antibiotics (quite common in 4/5 months of hitting it hard). It's hard (but not impossible) to get antibiotics without seeing a doctor, with the EHIC you can go to the local clinic, see a doctor, and get a prescription.
There are other options in terms of health cards you can get if you have a NIE and contract, but again I don't know much about this and you would need to ask someone elses advise.
