The University of Sunderland provided attendees of the event with a chance to stay in their Panns Bank student accommodation located just a short distance from Sunderland Software Centre. This was a great opportunity at a fantastic price of just £35.00 per night.
You also found a wide range of options nearby Newcastle Central Station — providing great links to the rest of the country by rail and air. Newcastle is only 25 minutes by Metro and gives you an opportunity to experience both cities.
