Hi there,
1) International house is located in the middle of campus, it takes barely 5 minutes to go lecture buildings. Rooms also seem nice. It also has a common TV room which other accoms don't have.
2) You do it in laundrette. There is a mobile app which you can see the timer, so people just leave.
3) I often walk, it takes 15 minutes or something. But there are also buses.
4) It is near the driveway, but still quieter than many places. No train sounds is a big plus lol.
5) CS student over here, pass.
6) Seems okay to me.
