Where to Live in La Reunion where it is pretty but yet offer City lif

Hi Everyone ,

Can't help but smile as I think about our upcoming move to La reunion!  we are planning to move in Jan 2015. I have been to the Island last Feb. out of all the places I been too I was more drawn to Saint-Denis from where to Live perspective . we currently live in Dubai ( you can imagine how alive the city is ) and after so many years a change will not be that easy. hence Saint Denis seems to offer  a less dramatic change. Yet I want to make sure we are taking the right decision. we are looking for a place where
- there are some expat ( we are mix family French & Egyptian) with 1 year old baby.
- weather is not too hot so happy to go uphill like Montgaillard
- good night life and busy city life if we want
-good facilities
so having said the above, do you think the call on Saint-Denis is good one ?

Thanks for all yoru help!
