DD was at Bristol.
Placements were about 50% in Bristol, 50% out. Accommodation out was provided free of charge. (Better than, say, Plymouth which also had placements at Taunton hospital but whose students were expected to find their own accomodation in the town.)
Bristol seemed fairly accommodating. Less well off students could asked for more out-placements thereby saving money. Similarly some, for health or other reasons requested in-placements.
There were complaints about some of the accommodation but there was no obligation to live in it. What I saw seemed fine. DD had two in-placements for her fourth year and two out for her fifth. She ended up renting a small flat on her own for her fourth year, as she had intercalated in London and then found that many of her friends had decided to stay put in their lockdown flats rather than seek to move. It is worth noting that finals at Bristol are at the end of the fourth year so it is worth being sure your accommodation is suitable for study.
Though actually the flat turned out not to cost a lot more than a shared student rental the deal was that she would live in University supplied accommodation for her fifth year placements. It would have been fine, but instead a friend offered her a cheap room in Bristol, and having missed two years of university social life because of lockdown, she wanted to have a final year with her friends. .
One thing to look out for is that GP placements can happen anywhere, with seemingly no logic. So commuting from Bristol for her final year worked in that the hospital was in one direction, the GP placement was a long way in the other.
Another tip is to consider first year accomodation. City centre and Clifton work better for medics. On GP day DD was having to get up at 5.30 in order to catch the bus into the city that allowed her to catch the once an hour bus to her GP placement. Unfortunately her flatmates were keen clubbers and would return at 2.30am wake her and eat everything in the fridge including her breakfast and packed lunch. She ended up getting a small car which she still has a decade later, and which made life a lot easier. That said probably only one in four medics drove, and DD was generally able to fill her car with three passengers, and claim back from the medical school.
