People always advise that you make sure you have enough money before moving to last 6 months, can anyone give me an idea of how much is enough?

I would look at about €8000 for the stay. This means you can pay bills for a fair sized apartment, get food in "touristy" supermarkets and still have time for a bit of fun.
Some apartments have hidden costs, others are all included.
I´ve used figures at €650 for an apartment (a nice one bed), you can go cheaper + €150 per week to live on. It depends what you classify as living.
Beer everyday, eating out every day and of course it gets costly.
I always over estimate things for living as you never know if something may go wrong.

when we first came over we `went for it´for the first 6 months and got through 15000 pounds. it just shows it all depends on what you spend it on but i do think cymmons estimate is fair.
