Hey Deo,
Saturday and sunday are alway PACKED in that area. Tons of people, everywhere in the streets. So if you are staying away from your place during the WE, and doing stuff somewhere else, then it's all good. But if you want to enjoy and chill in the neighboorhood - forget about it.
I visited City SQ and the things I don't like about it:
- mainly students staying there, sharing apts, so not very family friendly
- the place is HUGE, so when you're there it feels a bit like a factory with a huge pool in the middle
Positive things:
- shopping mall and Mustafa center nearby : there isn't a thing you'd need that you can't find there
- very close to town, to Bugis and to main expressways if you drive
- very close to all eateries you'd want
So if the location is essential, then you'll get used to the busy WEs I guess. otherwise, you should look somewhere else.
My suggestion is to go visit, or just walk around the
condo on a saturday evening or Sunday afternoon - you'll see what I mean
