For someone from Gdańsk this is laughable. The city is very car-centric. There are large areas of it that are just concrete with no green in sight. This contributes to absurdly high temperatures in the summer and difficulty of finding any shade. “Patelnia” (frying pan) has that name for a reason and it’s by no means the only such place. The city also keeps building glass skyscrapers which reflect sunlight onto the ground in already heat-stroke-inducing heat. It’s laden with huge intersections with 2-phase crossings, which you need to run through in order to go through in one go. If you fail, you’ll be stranded on a concrete island breathing in fumes from car traffic. Public transport is good if you can use the metro. But there are only 2 lines, so aside from maybe going to work you’ll most likely be using a bus. The bus is most likely to be going regularly late and overcrowded (god I hate 186).
