Manually entering address

[Elle-1]

Hey guys, 

I'm looking at getting a new iPad but whenever I get to checkout and have to enter my address, it won't allow me enter it manually. I live in a bunch of flats so I need to put my flat number in as google typically bunches all the numbers together. For example, whenever I put my post code in, the only option comes up is "Flat 1 - 4" which is kinda confusing for delivery people as they don't know which number its for.

Any way of going about sorting this or entering manually?
