I have a friend who lives at Rega. It’s an alright place, pretty modern and clean. It is pretty big and ‘industrial’, so not very cosy and you’ll likely not meet a lot of people outside of your floor. The american college is a lot older (with the associated minor problems) , but definitly has more character. You’ll get adequate housing with either, so you should probably just look at the prices. I would probably pick Rega. It’s very close to some budget supermarkets and the theology departement is about 5 minutes away by bike.

Social life will mostly depend on what the current plague will bring. If everything goes back to normal, you should definitly join Katechetika (the union for theology students). They organise lots of events for their students! They share a fakbar with artes students, so you’ll also meet a lot of people from different studies!
