I couldn't find a women's road category so I posted here.

I've just bought a Giant Avail 1 road bike. I'm 5 feet 2 but the frame size is XS, 43.5 cm, which seems quite small for my height (sizing charts say around 48 cm for 5 feet 2). The guy at the shop said the XS frame size is better for me because on the larger frame, S (46.5 cm), he could not get the handlebar/saddle height right.

I'd like to know what people think about this. The bike seems to ride pretty well and doesn't 'feel' too small.
