My city:

Pros:
-very safe
-excellent and extremely varied dining options
-proximity to great beaches on the ocean and the southern reaches of the bay
-climate never gets freezing
-lots of parks and green spaces, with the most elm trees in the world
-most extensive tramway network in the world, very efficient
-people are always very friendly and helpful
-very active and varied night life
-close to national parks with magnifiscent rainforest and wildlife as well as the great ocean road
-within 3 hours of ski resorts
-vivid subcultures (talented graffiti art everywhere, hip bars and concert places)
-heaps of sporting facilities

Cons:
-windy, extremely changeable weather
-the beaches closest to the center (on the north side of the bay) suck.
-high Australian dollar makes everything expensive
-almost no historical building of interests, very boring architecture
-suburbs that spreadout endlessly (radiates 40km from the tiny cbd), of which the outer reaches are full of unfriendly bogans
-the river is very polluted

Edit: Didn't notice it's only three things, I highlighted the ones that I think are most important to a new tourist.
