Comfort apart, are there any 'laws' on how many people can stay, in say a 1.5 room flat. When I was in a student home in FMEL last summer, for example, we were told not to entertain any night guests.

Also, if I already have a flat where I stay, then how could (in terms of procedures with the Canton office) a friend of mine start living with me.

Many thanks!

My rental agreement stated the maximum number of people.

Thank you Marie for your reply.

Is there any general guideline on how big a flat for 2 people should be?

The general rule at least in Bern, is that there should always be one more room than there are people. So in a 1.5 there shouldn't actually be more than 1 person so a flat for 2 people should be 3 rooms (2 bedroom) but how strict the rules are really depends on the building, landlord and so on.
