We cannot guarantee this due to our 'self-selection' allocation policy. The only possible way to do this is if you and your friend have been allocated to the same room release period. You would then need to self-select your rooms at the same time in order to choose the same Hall and flat.

If you cannot do this then you would need to just let each other know which Hall and flat you wanted to live in and hope that at the time of booking there is a room available in that flat and Hall
