A couple of things you should consider
Location: The university is centrally located in other countries that are within easy reach. I think it is very important for international students to visit other countries and experience other cultures.
Diversity: UoG is very inclusive and welcomes students from every nationality with open arms. Most of your colleagues will be European/Asian.
Culture: The University of Greenwich is blessed with Royal buildings, and a lot of English history is tied to that place. Cutty Sark. Painted Hall. Old Naval College, and right across, you have the Maritime Museum.
At the University of Greenwich, they've set high norms for education quality. Their staff includes a winner of the day's education, numerous innovative educator honors and several different National Teaching Fellows, a rank that recognizes exceptional education. The university constantly invests in evolving its three campuses.

Although the University of Greenwich does not rank among the top universities in the UK, it is still a good place to pursue higher education. Greenwich university is recognised for its programs in Law and Economics. The university in itself is a place of tourist interest. You have Greenwich Maritime Museum right across. The Cutty Sark, Old Royal Naval College history, the Painted Hall, Greenwich Foot tunnel, the O2 Arena, Canary Wharf, GMT Line, and to name a few.
