What makes a city livable or lovable?

Here is an interesting article from the Financial Times. Are all "liveable" cities lovable?


Here are a few traits that the author, Edwin Heathcote, provides: 


 1) Blend of beauty and ugliness – beauty to lift the soul, ugliness to ensure there are parts of the fabric of the city that can accommodate change.
2) Diversity – if lots of people are wanting to come to a city, there must be something there.
3) Tolerance – the only way diversity works but also an accommodating attitude to sexuality (gay communities are famously successful inner-city regenerators) and religion (there are signs of increasing intolerance towards religious minorities all over the world).
4) Density – density of habitation is crucial in ensuring density of activity, a vibrancy of commerce, residential and cultural activity.
5) Social mix – the close proximity of social and economic classes keeps a city lively.
6) Civility – impossible to measure and slightly against my stated notions about the benefits of friction but critical nevertheless. I once criticised the ingratiating politeness in the US and was told by an American who used to live in Paris that “it’s better to be told to have a nice day by someone who doesn’t mean it than to be told to go f*** yourself by someone who does”. Discounts any Israeli or Russian city from ever getting on the list.
