Stay of multiple members in studio apartment

Hi,
I am going to Sweden for 2 months work visa with my Company.
There I will be staying in a rented 1 BHK studio apartment.

My parents are coming to visit me for 3 weeks on a tourist visa. Can they stay with me in my apartment or there are some restrictions on stay of multiple members for short term.

Is there restriction on the stay of multiple members in 1 BHK apartment in Sweden for short term.

Thanks and Regards,
Bhaskar

For Visa purpose:

Go to www.booking.com

Reserve a holiday apartment for your parents.

Apply for visa with the reservation confirmation from booking.com

Once you get the visa, you can cancel your booking.

For actual stay:

**** Make sure you check with your landlord if its okay to have your parents with you*** Short trip should be OK in my opinion.

Not all embassies accept booking.com reservations as you don't need to make any payment for booking through this website. So check with embassies whether they have any restriction.
