Well it was a 15 minute walk for me to get to school back in London, so I've only ever needed to walk 30 minutes to get into Uni when I was living in a house we rented for our second year (I was only there to a couple of weeks to do my retakes which I failed...)
Hillside/Woodside might be a tiny bit closer to Uni than Stoke Bishop halls but the way to Hillside/Woodside is quite hilly if I remember correctly as its situated across the river ie. you actually have to cross Clifton Suspension Bridge to get there!
If you can get over the distance problem, I'm sure it's a great place to live.
