Depends on what you want from a halls and what your main concerns are living away from home. I knew I definitely didn't want to go for catered, very limited food options (usually kind of grim imo), if you're not there at a certain time for meals then you don't get to eat etc lol. I knew this wouldn't work for me cause I feel like if I fancy eating something specific I don't want to have a random canteen meal that i might not even like, and I also had a job in first year so my schedule wasn't as flexible as unemployed students. But basically: most halls in Bristol are all grim...Some of them you just pay more and are surrounded by tories, but hey if that's your cup of tea then go for the more expensive ones. I lived in stoke bishop and they all have stereotypes.
Churchill: posh, nice courtyards
Badock: druggy, rooms are a scam for how much you pay
UH: least amount of private school ppl, best bar in all of stoke bishop
Hiatt baker self catered: usually normal ppl, some posh but on the whole they're nice
Hiatt baker catered: more posh people than SC but looks like an actual prison on the inside
Durdham: people used to call it deadham cause it had the reputation for being boring but the people are usually fine
Wills: full of tories - if I had to pick a hall I would want to live in the least out of them all it would be wills
I honestly don't know which I would recommend for the best catered experience, as like I've said the catered experience never appealed to me. I think churchill is probably technically the nicest in terms of rooms and grounds, dunno what the food is like. However, if it was me I would probably pick HB if I had to pick a catered, just cause the people are more normal than the likes of wills or churchill lol.
