Renting: Windows too high to open, who buys the stick?

We've moved into a new flat and the windows must be at least 3 metres high, and on top of the kitchen unit so we can't use a ladder. This is unreachable for either of us and would clearly need a stick. Is it out of hand to expect the landlord to provide this?

To add to that, it is a double window. We can't seem to open the outside window, only the internal one. I have no idea how this is supposed to be navigated - if anyone has any advice or recommendations of where to buy a stick if it does indeed fall on us.
