Tile Hill as in near the 12 route with the huge Sainsbury's and a mass of eating places (McDonalds/Pizza Hut/KFC)? Well, I suppse you won't know if you don't know what's in Tile Hill, but so far as I'm aware it's alright. Nothing spectacular, but pretty convenient.
It's not nearly the most popular student area in Cov (that would be Earlsdon, obviously) but you'll have housemates to be sociable with. It's within a reasonable walking distance of campus so you may not feel a ~£180 bus pass is justified.
