Ke krátkodobému ubytování tyto informace nejsou nutné,pokud na nich hostitel trvá,nedávejte skutečné,ale změněné,mohlo by se jednat o podvodné vylákání údajů.Hodně štěstí.
@Sujin6 Many European countries and some others require that all foreign guests are registered with the local govt. office. That is why your host would be asking for this information, he requires it in order to be in compliance with govt. regulations. I'm sure you could Google the exact laws or at least a list of which countries require this info from guests if you wanted to research further.
I am a host in Milan and I confirm you that is mandatory by law to register every new guest. The information your host asked you is exactly what we need for this process. Is the same for hotels.
