Thats a very tricky situation apartment + rent, would be nice to see folks coming with solutions for this.
I stay in rented house 2nd floor. Though my owner is supportive and allowed to install dot I couldn’t because of space issue and also thought about re i stalling amd stuff. So I dropped a pug box from my floor to ground floor and portable charger. Whenever I require I use it other wise pull the plug box up and keep it.
I routed the cable from outside to my plug point inside my house whivh is fixed and the excess cable along with box is rolled and kept aside. I will try to post a picture tomorrow since I have to do it from browser.
