My Czech host is asking me to fill out a migration form

[Nadya54]

Hello,

My host in Prague, Czech Republic is asking me to fill out a migration form "in compliance with Czech legal requirements (§ 99 až 102 zákon č. 326/1999 Sb., o pobytu cizinců na území České republiky). We are not allowed to accommodate you unless the migration form is filled out correctly. Non-fulfillment of this legal condition may result in reservation cancellation without reimbursement. Kindly click on the following link and fill out the migration form for each guest individually: https://login.smoobu.com/en/online-check-in/check-in/8f59823cf1eec7ab7d4584071a4fb452dd529081"

The form asks for a lot of personally identifiable information.  I tried searching online, but nothing coherent came up

Is this legit?

Thank you.
