Exchange student find a roommate

Hi! I'm an exchange student from Monash University and I'll be studying at Cardiff University for one semester.
I'm clean, quiet, and respectful of shared spaces. I'm quite easy-going and enjoy meeting new people, but I also value personal space and a calm living environment.
I'll mostly be busy with university work, cafés, travelling around the UK, and exploring Wales during my exchange. Looking for a tidy and friendly flatshare with good public transport access. Reliable Wi-Fi is definitely important for me.
Deal-breakers would probably be heavy indoor smoking or very loud parties late at night.
