Checked out Salz und Brot - Cologne's where I lived for quite some time and where I'd like to return to in the future. Family just didn't make it viable - the rent is just too high/we can't afford it and moved elsewhere.

And just to confirm the craziness the first apartment I checked out in Cologne [1] (for fun, not seriously planning to move atm) requires you to pay 1300 EUR for the kitchen (sure, makes sense), a bit of furniture (common) and - I wonder what they're smoking - the floor (Echtholzboden). You're "buying" the floor in a rented apartment? Look at the pictures. Are you going to take that with you when you move out?

Not sure if that's something you care about, but you mention that this site is a partner of yours. The UI's broken in my browser (Aurora/Firefox Nightly) - if you got contacts that might be something to look into? [2]
