I lived in Leodis in my first year. It is pretty nice, very close to campus (10 minute walk to the outskirts, probably 20 minutes to law campus). There are 9 blocks, 8 of which have 7 floors whilst the 9th (A Block) has 5 floors. 6 people to a flat, two flats per floor. The ensuites are good, bedrooms a nice size, and you have plenty of space. Leodis is one of the most populous accommodations so there is always people around, and it is plenty sociable.
I didn't get on great with my flat, so my view of Leodis is definitely a bit altered by this. But most people I know had a great time and would definitely recommend Leodis. I think it is a bit expensive for what it is (somewhere like Lupton is better value for money), but halls are really expensive but deffo worth it for the experience. Leodis is basically a slight downgrade from Central Village (in the sense that it is slightly further from the middle of campus and some of the blocks are less modern) for the same price, but you are far more likely to get accepted to Leodis than you are to CV because less people apply for Leodis.
Overall, Leodis is a good choice! I enjoyed my time there on the whole, and we didn't have any major problems. Some blocks, eg J block, are more modern than others (eg B Block), and A block has the biggest rooms but no lift. I reckon you could be very happy there.
