Lyddon Hall is right on campus, you can roll out of bed and go to the union/refectory and most important buildings straight away. I realise that you're interested in other halls, but I'm just letting you know because Lyddon is catered, so no hassle about buying food or cooking, and it's so close to everything that it makes life considerably easier. Basically, if James Baillie and Leodis are oversubscribed, you could consider Lyddon!
