DS is also just very keen to move on. he's not quite as organised as bigwoolyjumpers DD but is getting there.
He is so close to securing his preferred accommodation, just seems to be a little set back in the booking system.
Given the uncertainty of how much F2F time they will have, I think his choice is a wise one, lots of communal areas for study, and different areas for relaxing and hanging out, plenty of outdoor socialising areas, and a more cosy living space with flat mates.
One halls looked so industrial, with tiny cell like rooms, the desk wasn't even big enough for his computer with one screen let alone two, to get out you'd have to move the desk chair out the way just to open the door. I couldn't imagine if he had to do a lockdown in there, or even be doing most classes from his room.
