We got our address from our postman (not a windscreen wiperer or a wrought ironer, more of a "sit on my motorbike beeping the horn till they come out and get it" sort). He counted from the main road down to ours, deciding that we are officially number 5.
So we informed everyone in the UK, number 5, sokak 994. That included all family, UK banks, the lot.
Imagine our joy when the belediye men turned up 3 months later with a bag of blue house numbers and a tube of silicon, sticking one to every house in the street. Yes, you guessed it, number 7.
