Honestly guys. Stop stressing about which halls your going to be 'stuck' with. Firstly, you can't do anything about it anymores. Secondly you ARE going to have a great time in halls. Us Re-apps make sure of that.
Pembridge is a great halls with a great atmosphere. Due to the large numbers of people using each kitchen it is VERY sociable. Both the house 28 kitchen and the games room tend to become social areas, which kind of divide you into two groups, the house 28 kitcheners and the house 32 kitcheners.
Also the halls is one of the smallest in Imperial, which means most people know each other. Pembridge also has one of the highest aminities funds which adds to your rent, but also adds to the alcohol that is present at parties.
Just be aware that because its quite small, things go missing very quickly in Pembridge. Do NOT bring expensive cookwares to Pembridge.
