Good luck for your moves, new neighbours to be! I came here 15 years ago and I love it - it is such a friendly and laid back place. This is my thoughts on the areas I know well:
Mumbles/Langland/Caswell/Bishopston - expensive! Very attractive, safe, lots of nice shops, places to eat etc. Great clothes shopping as long as you like Fatface, SeaSalt and Joules! Walking distance to lovely beaches and quite outdoorsy - lots of paddle boards and kayaks. Rather middle class and yummy mummy and not ethnically diverse. The schools are good Oystermouth and Newton have strong PTA's and good teaching with stable schools. Kids do well. Bishopston or Bishop Gore are the catchment secondaries - both excellent.
West Cross - Mumbles slightly poorer neighbour. Generally walking distance to Mumbles. Becoming more gentrified. Not much going on there.
Mayals - near West Cross, on the way to Bishopston - similar vibe to West Cross. Nice but not much happening.
Sketty and Uplands
My favourite areas. Near to town and walking distance to the sea front. Good range of housing stock and both neighbourhoods have shopping areas with cafes, restaurants etc as well as banks, chemists and so
on. Varied housing stock - lots of Victorian but also turn of the century and some newer stock. Cheaper then Mumbles. I like it so much because it is safe but lively and diverse. You are fairly near St Helens Road with all of the wonderful ethnic food shops and cafes. Yes, the students can be noisy and messy but I love the energy and fun that they bring - and finding a good babysitter is easy! Great parks - Cwmdonkin, Brynmill and Singleton. It is less middle class and feels more real than Mumbles - there are lots of professional families living in Uplands/Sketty, but there is also a traditional Welsh community and a large Asian and Chinese population.Oh and great schools - Brynmill Primary is fab! Can you tell I love it!
Monthly produce markets take place in the Marina, Sketty, Uplands, Mumbles, Penclawdd and possibly more.
The amazing covered market (the only good reason to go into town) has amazing fish and seafood, meat, deli and bakery stuff and fruit and veg.
Shopping other than for food is rubbish in the centre of Swansea - go to Cardiff!
LC2 - leisure centre with soft play, pool with flumes/waves and indoor surfing, a climbing wall and a members gym and spa. Loved by all kids - avoid on a rainy Saturday because it will be rammed.
And the beaches, oh the beaches!
Keep us posted - let me know how you all get on.
