Those who have stayed in a Paris hotel probably know that the front may look great, but the view at the back can be quite horrible. Polish housing estates are different from this. As a rule the front looks horrible, and the back is a shocking wasteland of mud, cobblestones, burnt-out pvc wastebins (imagine the smell) and rubbish containers. Talking about smells, this is coal mining country where not all the pits are closed - yet. Coal is still used for home heating, so every now and then I catch a sniff of coal smoke. Nice if they don't overdo it!
Added to this, and changing the subject abruptly, here's a slide show I found. It's about The Who of course.
