Hi there,
I'm not at warwick yet but I'm starting in September too
Personally I'd say a lot of the accommodation choices at warwick seem pretty bad, value for money wise, they're all quite overpriced for what I've seen of them. So it's really down to what you want, the shared bathroom accommodations are much cheaper compared to ensuite so if you don't mind a shared bathroom then go for them.
The cheaper shared bathroom accommodations include: cryfield standard, rootes and tocil which are all around 120/130 a week
The cheaper ensuite accommodations are heronbank, Westwood and sherbourne. But they're all around 190 a week 🫣
Honestly though from when I went on open days the only ways accommodation vary is in shared/ensuite and the number of people sharing a kitchen other than that the rooms are all very similar but some are slightly larger than others.
Also check the contract length because some are shorter than others so you pay for less weeks in the year
