Digs

I have just been accepted in a MA in Screenwriting in Galway.

But, my life is pretty much set up in Dublin as I've been studying there for three years. I have a girlfriend there, a band that's just starting to get going and all of my friends are still there studying.

Screenwriting is only two days a week, monday and tuesday.
In a perfect world I would love to find someone who would consider shacking me up for two nights a week.

I would pay of course, but from I've found so far hostels/B&Bs would not be worthwhile as it would be about the same price for a week's rent on a room.

Does anyone have any tips on what I could do? Would like to stay settled in Dublin, but without paying rent on a second room in Galway...
