I have a friend who did it in his apartment and it worked out great. The thing is really the wall prep like the person before said - it needs to be spotless clean, no dust, and if you have imperfections like little holes or bumps they're gonna show through the PVC. I kind of compare it to prepping a surface before putting a fish fillet on a plate, if you slack on the prep then all the work after that is compromised.
The actual installation isn't hardcore, you glue as you go, you press down hard so it doesn't bubble and you use a spatula or scraper to get the air bubbles out. The real challenge is when you get to the corners and edges - that's where you gotta be a bit careful and take your time. If your hallway has weird corners or tons of stuff on the walls (light switches, outlets, etc) it's gonna take you longer but it's still totally doable.
After that it's mostly about patience and not rushing. If you feel like you're not comfortable or your walls are really uneven, a pro will do it faster and without stress. But personally if you have some basic handy skills and time on your hands, go for it. I've already messed up tons of projects in the kitchen and anyway in hockey I learned that mistakes are part of the process, so no need to panic.
