Bristol Uni Accommodation Help

Hi
I’ve got an offer to study dentistry at Bristol, and I was wondering:
- Which university residencies are closest to the dental hospital
- Which university residences at Bristol are good/bad (opinions)
- Do i need to apply for accommodation asap (even though they say it’s not first come first serve) in order to be more likely to get my chosen accommodation?
- Oh plus is the ‘basic’ level of accommodation at Bristol still good? Some pictures look completely fine whereas others look a little questionable haha
Thanks
