Good, clean, solid accommodation. Location under 10min walk from the train station and near Messe, but perhaps 20min walk to the city centre. Right next to a fairly busy road but the windows do a good soundproofing - still, I needed earplugs.
Some confusing information about the reception opening times as it looked they haven't updated the description / follow up messages from the lockdown periods. In the end it was open during the day as well.
