Well, if you go out early enough. Normally during the day tons of parents with kids are roaming around. I see it from my window, because unlike them I do have to work :/. So, those pics are a bit BS, streets are not that empty during the day.

Looks just the same in Oslo, Norway:(

Being an introvert to me this looks clean and beautiful but I imagine walking down those streets etc. would feel eerie and scary especially at night and with ones own steps echoing in the silence and emptiness. I bet movie studios and would-be architects would love to use this time of free and empty places to shoot movies and take pictures respectively

Wow, that's kind of creepy. But cool at the same time.

The plaza on the picture with the sky scrapers view is called The Frying Pan (Polish: 'Patelnia') - it is the very center of the city, main subway station, nearby local and national railway stations, a lot of trams and busses. Usually it's overcrowded with people even at night during the weekdays. Incredible pic.

Polish women are hot. It's a fact.
