This one was a bit of a struggle. It is a city alongside a major river, a city in Europe. It could be Cologne, it could be Basle : I visited both during the early 1980s. It took a modest Googling of hotel names to pinpoint the Swiss city of Basle. Our next door neighnours in Sheffield had moved to Basle and we went to stay with them. Once I have pinpointed the city the flood gates open and the memories come flooding back.
