I live in Cardiff (Rhiwbina). I think Califrau used to so maybe try her...
I think Howells has a great reputation. It is in Llandaff which is a lovely area to live in, quite green, good for families (home of Cathedral and BBC, lovely row of village shops, nice properties with reasonable size gardens, easy access to M4, good bus and train links into town). Town is about 4 miles away.
I'm a SAHM and my husband works in IT, so can't really help you with world of finance salary - but 60K sounds like a lot of money to me!
North Cardiff generally nice (Rhiwbina, Llanishen, Lisvane), good for families and quite green. And good schools. Radyr and Llandaff nice. Penarth (a little further out but by the sea). St Fagans lovely (home of folk museum but not quite so central. Cowbridge too but much further from the city (12 miles or so?)
Post or email [email protected] if I can be of any further help. Do you want me to suggest estate agents so you could get an idea of property prices?
I've been here fifteen years and have always enjoyed it. It is a growing city which seems to offer something for everyone. Loads of people stay on after university, which I think is always a good sign.
Hope it all works out for here.
