Chancellors is one of the better ones. Its right next to John Anderson (or James Weir... I can't remember, always get them confused, its the K building XD) and has a awesome archway XD They also have a lift inside. The living area is also nice, one of the flats I went to had 2 ovens etc. Not been inside a room. This year they also do have quite a few parties. But its all in walking distance to wherever the party is. Birkbeck is just down below and Forbes is beside and James Goold/Blyth etc and the other way.
Can't say much on James Goold though, except that its at the 'outskirts' of the halls where its situated.
