If you are arriving by train, walk to Piccadiily Gardens and catch any bus going to the University - they are every few minutes.
Accademies 2 and 3 are both housed in the Student Union Building, and Academy One is the building next door. They vcarty in size 1 down to 3, but all are fine for seeing bands.
There is a bus stop right outside to get you back to Picadilly Gardens afterwards.
If you are comng by car, the University is just down the road on the opposite side from the BBC building on Oxford Road .
have a great time!
