Gonna copy my answer from another thread here, since (I think) it's a pretty good overview on accommodation at Exeter.
It really depends on what you want out of your first year accommodation. For background, I'm a 1st Year student at Exeter, though I'm living in private accommodation off-campus, so I can't provide any first hand experience of living in any of the specific halls on campus. What I can do, however, is provide a fairly unbiased review of all the halls I have visited, and give their pros and cons.
First off, East Park. One of the newest accommodations blocks, East Park is very nice. It's got Games Rooms, Study Rooms and most of the facilities are fairly modern. It has 2 types of rooms; Standard (shared bathroom) and En-suite. Standard rooms are about 9.6m², En-suite are about 12.7m². Standard rooms are flats of 8 to 10, and En-suite are 5 to 8. It's on the east side of campus (shocking, I know), so it's decently close to most of the STEM buildings (other than the Physics building), but it's a bit further away from some of the Humanities buildings (though it's still close to Amory). It's also built on a big hill, so depending on whether you live at the top or bottom of East Park, you may have to contend with a lot of stairs to get where you need to be.
Next up is Lafrowda. Closer to both the center of Streatham and Town, it's one of the more popular and well known Halls, and it has a reputation for having a lot of parties going on, which is deserved because it does. Quite close to Lafrowda is also Rowe House, which is similar in location and style, though the rooms are a bit smaller (about 12m²) and all En-suite with Double beds. Lafrowda has 3 types of rooms; Standard (10.5m², up to 12 people per flat, single bed), En-suite (14.7m², up to 8 people per flat, single bed) and Studio (16.1m², room with kitchenette, 3/4 double bed). Both Rowe and Lafrowda are fairly popular, but don't have the Games Rooms or in-hall Study Spaces that East Park has. That said, you'll have a communal space in your flat where you can study and play games, and there are various places around campus to do so as well, so I wouldn't worry too much about not having them.
Finally, we have Birks, Duryard and Moberly. I'm lumping these three together since they're all on the west side of campus. This means that they're gonna be a bit further away from campus center and a bit further away from town center, though they do also have less parties going on, so if you're not so much into that then these may be the ones to go. Since there's three of them and this post is already getting really long, I'm just gonna go over some quick points for a few of them. Birks has a shop fairly nearby, and is fairly close to Kay House, which is a music practice area. Duryard is also fairly close to Kay House and is close to Birks, only offers En-suite rooms and is probably the furthest away accommodation from campus center and town center. Moberly is one of the newer accommodation buildings, only has standard rooms but does have some quite nice facilities.
Pictures and virtual tours of all the accommodations I mentioned are on their pages on the Exeter accommodation page. I can't comment on anything to do with international students, but I hope this helps, and if you have any further questions, feel free to ask! Also, sorry about the text dump, tried to be as comprehensive as possible.
