Hi! I see you posted this a while ago so you may have already decided but thought I’d reply anyway just in case.
The nicest halls are definitely the newer ones (willow, juniper, beech) however they are very expensive. I think they are all en-suite rooms and shared kitchen unless you get a studio. Flats are generally 5 or 10 people. I have heard people say these flats are a bit more boring however I think it just depends on who you’re with.
I think there’s some newer ones at Alexander court but I don’t know much about them.
The other ones at Alexander court are decent too but a bit older. The flats that I’ve been in there I think we’re 6 people, shared bathroom and kitchen. The only thing with Ali court is that it is quite far from the rest of the campus about a 20 min walk from everywhere else but a lovely walk none the less.
The other accommodations are also older and vary between en-suite and shared bathrooms. When I lived on campus Andrew Stuart Hall (ash) was where a lot of people went to pres etc but there’s stuff going on in all the halls so probs depends on who your friends are.
Hope this helps!
