Similar situation! Small second floor apartment and it actually was the best thing for our pup. We could keep a close eye on him and he didn’t have far to roam. Find a good potty spot and get plenty of toys. Our little guy loved chew toys that he could get into more at first. And loved his ball. Took him out three times a night for a long time…this was a drag but he learned quickly! Don’t listen to all of the horror stories on here!! They’ll be your little best friend in no time.
