Exeter self-catered accommodation 2022

It'll really depend on what course you're doing and where you're based. Some things to note about each of their rooms; Moberly doesn't offer en-suite (though as you said, that's not an issue for you), and has the smallest of the rooms at 9.5 square meters, as well as the townhouse rooms having a single bed. East Park is the newest accommodation building, it's a bit more expensive than Moberly, but the rooms are a bit larger (9.6 square meters) and it has three-quarter double beds. Birks rooms also have single beds, but they're also the largest of the rooms at 9.9 square meters.
Distance wise, Moberly is the furthest from campus centre, and East Park is the closest (though it's a range of 10-15 minutes, so not a huge difference).
I've never visited Moberly or Birks myself, but I have visited East Park since one of my friends is staying there, and I can tell you that it is nice. Since it's the newest, it's fairly modern, and it has Games Rooms and study spaces that you can book in the building.
Hope this helps, and feel free to ask if you have any more questions!

Thank you so much, this is really helpful to know, especially room sizes as I couldn't find that anywhere online! What are your thoughts on St Davids?
