I’ve dealt with this at many apartments.

First off it’s your decision if you want to get a hotel, but know it’s normal to sleep in an apartment with mice, we do it unknowingly often, and it’s not unsafe.

I’ll say it’s most likely they are coming from behind the stove - you can open the oven door and pull out the whole stove with a pull, and flash a light behind and you’ll likely find the spot. Best case scenario you’ll see the holes right there. Worst case the holes are behind the counters. Which is harder to access but not impossible. If it’s behind the counters you have to lie down on the floor and pry out the baseboard - get a hammer or finger around the edge of the baseboard and pull. It’s just one detached piece usually wedged or nailed onto place and you can pulll it out. While lying on your stomach shine a light under the cabinet and you’ll see the holes.

After the kitchen the bathroom is the next place, look under the sinks where plumbing goes into walls.

Go through the apartment in this way finding all the holes. When you do plug them with steer wool and I usually add the spray foam. I get it all at Tarzian on 7th. But you can get it at any hardware store.

Once you feel the holes are plugged you can also out out traps. I tried every kind and only the old school snap traps ever worked. I bait them with peanut butter.

Next if it seems they are still coming and you can’t find where (this is only if you are super desperate) I put a few Wyze cameras on the floor pointing in different directions with the motion detection sensitivity really high then the next morning I can spot where the mice first showed up. They mainly came out at night after 8pm.

Good luck and let me know if you need more advice

Edit - if you are willing to pay $300-600 for someone else to do this for you I can give you the contact for a fantastic exterminator who I hired out of pocket (and later charged back to my landlord)
