I live in a house from 1900 and the stairwell is where you sense it the most. Most of the details are left and next to our entrance door, there is a door to our neighbours' shared toilet.
Ps. The Pet Shop Boys are performing live in Berlin tonight to celebrate their new album, you can watch the show online here at 9pm (CET). I wasn't lucky to win tickets (you weren't able to buy any) to the performance, but I have been lucky to see them live several times before.
