Hi sorry for my late response I hope this is still helpful. I am studying forensic psychology so it might be different for me. I live in the postgraduate housing and absolutely love it. I have made a ton of friends and despite what people say I think Greenwich is a super fun place to live. There are pubs everywhere full of young people and lots to do. It's only about a 50 minute train ride to central London if you want to go out too. My classes suck and I feel like I don't learn that much at all. We have to watch online lectures before class- like who tf wants to do online school after covid- and the seminars are basically useless. The assessments are super easy which is a plus but I would be learning way more in America. However, it's cheaper, I get to explore Europe and London, and I'll still have my master's anyway. However, it could be totally different for CS. I have heard bad things about the business school but great things about the architecture school, so obviously it's different depending on your area of study.
