3. High Rise Flats
Being in a high rise flat would definitely be a decent call if they're zombies taken over the world. Of course, you have to deal with the potential problem of the dead neighbors who may come after you, but as soon as you sort them out and you close that door behind you.. and then maybe barricade it a little you should then be nifty! It gives you some space, and if you manage to clear out your surrounding floor you would have even more room to work with. Barricade the floors entrance ways and you're sorted!
