So my visa will expire soon and I want to get the one month tourist L type at the PSB

but I had some troubles here about my appartment. I had a fight with my landlord so I had to leave my appartment and because i am only here 2 more month I just sleep at my friends place now. I still have the residence card but I don’t know if I am still registered to that appartment.
And in case something goes wrong the first time, can I go there again 1 or 2 days later with the documents from a hotel which is confirming my stay?
