Not sure where the original photo is from, if it is actually Warsaw, feel free to delete. However there's no location on it, so I'm uploading from Warsaw. (Mazowieckie)
It is near Poniatowski' bridge in Warsaw. https://www.google.com/maps/@52.2336071,21.0302228,3a,75y,288.36h,99.68t/data=!3m6!1e1!3m4!1sHMF5AB1s2_KkZRwEJ0X-dg!2e0!7i16384!8i8192
