Yes I got Nixon Court last year. I shared a flat with 10 people (all girls). It wasn't as hectic as I thought it would be, but we had major heating issues! They don't have modern central heating, instead they have these very large boilers that look like dishwashers, which make the kitchen really hot, and when its already warm outside, not very nice. You can't leave your food out in the summer! But honestly it wasn't that bad at all, its so close to uni, Morrisons, Odeon, Nandos and the city centre - big big pluses! Plus you get to stay over the summer, most Oadby people have to move out completely.
They try and group first years together - and with people who are similar to them, e.g. one of my flatmates was also from Manchester, who lived 10 minutes from me
Also 4 of my flatmates shared the same course. I was told N.C was going to be full of international/post grade students, and if I'm being honest, it probably was, but all my flatmates except one were 1st years, and from the UK.
Its not as 'loud' as Oadby but uni is what you make of it. I only had issues with the flat itself, not the people I met and for the price, its worth it!
Don't worry about sharing toilets and showers, its fine, you get a cleaner in every week.
