Thanks for all the comments.
I'm reluctant to put a tension pole up in case I mark the wall. It would also mean buying 2 sets of curtains that won't fit anywhere in our next place.
Property is at such a premium in this area that I cannot find anywhere that will allow a short term let, most places insist on a 1 to 2 year let. Also they would not allow me to keep Beano.
Col, if I demand to be allowed to put curtains up I'm pretty sure I'd be asked to leave as there are other people waiting to move in here.
Ellen I can't see the audiology dept providing cochlea implants, but I will ask at my next appointment.I
I hope I've answered all your comments, I apologise if I've missed any.
