Yeah, had a look at Cairncross and I didnt like the large flats that much...think its just that they looked like a floor in a youth hostel to me...but then you are right, its sooo much easier to get to know people when you live together with 12 people..plus there will be good house parties as well...and its bad if you dont like your roommates if there are just 4 of them =P
..but well...hope Ill live together with nice room mates =)
