I'll repeat roughly the post that I wrote in the Secondary education topic - as much for anyone else who might be interested in the area as you 
Langside seems to be a good primary school - but I only know it by reputation via the parents at the local rugby club who have kids there. Shawlands Primary is good too, as is Battlefield Primary. (My ds went to Glendale Primary but it feeds/we're in the catchment for Bellahouston Academy).
But I have nothing but praise for Shawlands Academy. Ds has just finished S6 there and is off to Aberdeen Uni on Sunday (
). He was a placing request - should have gone to Bellahouston Academy. It's a great school. Encourages strong academic results but more importantly aims to to turn out well rounded individuals. We'd have done a placing request anyway but the fact that it was a School of Rugby sealed it for us (or rather dh, as he'd said he wanted ds to go to a school that did rugby from S1).
It has a friendly rivalry with Hyndland, which gets similar results (although the headteacher would insist that Shawlands is better
)
Shawlands has a very mixed demographic - from a lot of SIMD1&2 (eg Govanhill) to the leafy streets of stone villas in Newlands, Strathbungo and parts of Pollokshields. It is proud of that demographic as it is part of what creates the ethos of the school - adding value to all the young people. The head teacher describes it as ranging from kids whose parent is a millionaire to those who literally don't know where their next meal is going to come from 
There are apparently 55 languages spoken in the school and the British Council has described it as the most international (state?) school in the UK. 
I think it's now the 2nd largest secondary in GCC (after Holyrood) and is now very much at capacity (so placing requests will become more difficult). The advantage is that they are pretty much able to offer just about any SQA subject. 
If you want to get a feel, you can watch "Our School" (think that's its name
) on CBBC as it was filmed there last year.
I love the Southside (even though I was brought up in Bearsden/Milngavie and went to Bearsden Academy) with its parks (Quuens Park, Maxwell Park, Pollok Park) and good transport links - and good schools
Shawlands has become quite a vibrant place as well for eateries, cafés and some wee arty shops. Not quite the West End - but still great in its own way.
Hope that helps! Any more questions, feel free to ask.
