A friend put some photos of his visit to Rotterdam on his blog. They were rather drab, because the weather was bad the day they were taken. I lived in Rotterdam for three years, from late 1977 to late 1980. I still have a soft spot for the place and the people.
On my last visit there, in November 2019, I took these photos in central Rotterdam.
And this is how I got from Schiphol airport, where I was staying, to Rotterdam and back. Comfortable, but expensive - there's a new direct line (only 25 minutes), but you have to pay a supplement to travel on it.
