I was extremely surprised about Bratislava – this city is quite photogenic! Last time I was going to Bratislava was about 10 years ago and did not have time to walk around to take some photos.
On this trip I flew to Vienna and rented a car. The main idea was to drive back to Switzerland form there staying every night in a different city until I was in Bern. It seems like there is a problem with the VAT when getting back to Switzerland so I decided to drive thru Czech Republic to Bratislava.
If you want no people in the photos, either go out very late at night or extremely early in the morning. Sometimes it is already enough to go out again when during sunset, when people go to restaurants for their food.
