To everyone saying it should be a 50/50 split between rooms that's just being naive.
It's not just the bedroom but the entire living space. Suddenly you've got an extra person using up time in the kitchen cooking and washing machine, taking up a seat in the living room and even just as simple as having their say as to what's on the tele.
That someone only paying half of what you do on rent but still having the same amount of say as to what happens in the flat would personally annoy the hell out of me.
It shouldn't be but money is ultimately an issue for people and, in this specific case, having someone pay £350 less than you a month towards the flat but still having all the benefits apart from having to sharing a bed is a bit crazy IMO.
Oh yeah, and it's not uncommon for people to pay more on the rent for getting the bigger room. So like you're saying OP I agree with the compromise you've come to regarding this and the sleeping arrangements.
Also, I agree with Pug, sweeten the deal with him - little extra for you for double the saving for him. The fact you're both on the same wavelength speaks volumes, regardless of anyone elses opinion in this thread
