IUCr designated hotels are peppered within a 10 km radius around the conference venue with convenient shuttles at pre-designated hours (see http://www.iucr2017.org/accommodation/). But for those who prefer the road not taken, here is a list of older, iconic hotels in the city centre. Transportation to HICC would have to be by taxi though, at one’s own expense.
