My friends didn't have the best experience of Norfolk Park. A burglary next door and mouldy bathroom downstairs and things. It's miles from Collegiate Crescent campus, and a good 20 minute walk (involving a big hill) to City.
The Forge is nice. It's big, better suited to someone who wants more of a social feel. I stayed there one summer when my building (The Anvil) was closed. I had one of the disabled-friendly rooms on the ground floor, which had a wet room style bathroom. The water would collect at the base of a little ramp every time I had a shower, and eventually spilled out onto the carpet. Nice! So yeah, avoid those style ensuites. It has a lot of facilities - there's a gym, common room, main reception. Sainsbury's Local, Subway, Greggs right on the premises and an Aldi across the road. Has both 3/4 double and single rooms. 10-15 minute walk to City Campus, the same to the city centre, and the same to Collegiate Campus.
The Anvil is where I live and I've been happy here so I've stayed for three years. All the rooms have 3/4 double beds. I live in a flat of 3 (though there are studios and flats of 5 as well), so it's relatively quiet (which suits me, as I'm 25, and I have to wake up at 6am a lot for placement). It's a 10 minute walk from City Campus, and a 20-30 minute walk to Collegiate depending how slow you are - but I walk it all the time happily. Nice and modern, warm, mostly quiet. Last night some silly person had their TV blaring at 2am with the window open and the sound carried right into my room - quick call to security sorted it.
The people who manage The Forge/The Anvil are a bit rubbish though. Never had maintenance problems at The Anvil, but they did forget to mention I needed to get my key re-programmed at the start of my summer tenency (so I was locked out) and again that September. They also wanted me to move out of The Forge over the summer by 10am at the latest but wouldn't release my room at The Anvil again until 12. Just daft admin things really, wasn't a big deal, but there's definitely a bit of "left hand not knowing what the right is doing" at times.
The Trigon I've heard good things about - very similar location to The Anvil so same sort of times for getting places. Again it's a new property.
Pinnacles is a bit more out of town the other way - I wouldn't live there if you were going to be based at Collegiate really, but it's meant to be nice.
Victoria Hall is bang in the middle of town, so food and shops are nearby - closest supermarket is probably a Tesco Express on Division Street which isn't far at all. It's easy to get to both campuses - I'd say Collegiate is probably a 15-20 min walk, and City is 10-15.
