Hi Caz and Ian
A few things to look out for apart from the obvious broken tiles etc
Cupboard doors ---- check fixings are tight and doors are not shaky
Under kitchen sink ---- check that pipework is not just finger tight, do the same for bathroom
Bathroom ---- check that the pedestal and toilet are firmly screwed to wall/floor
light switches ---- check they are not loose or broken
patio doors ---- should slide easily and close properly and all door locks work
I'm sure there are plenty more but the most important one in my view is to check the slope of the terrace. If you can get hold of a spirit level check that the slope runs away from the apartment and not into it, if no level is available throw some water on to the terrace and see which way it runs and that it doesn't pool. From previous posts it looks like there aren't that many problems with build quality so your snagging should be reasonably stressless.
Good luck with your snagging and enjoy your place in the sun.
Cheers
