Super cute, but I would avoid the pee pads. 21st floor means you'll have to be pretty discliplined. For a rough estimate, every month of age is how long their bladder can be reliable in hours (ie: 2 months old, they can be left two hours between potty breaks). The problem with puppy pads is the dog learns its OK to pee inside! What if there's no puppy pad? What if it smells different because it's someone else's home? No problem! I'm allowed to pee inside! It makes proper housetraining later THAT much more difficult.
Good luck with your little guy! He's super cute
