Apartment living with a 15 month old who runs to get around and noise complaints from downstairs neighbor. It it possible to teach our baby to stop running?

To set up the situation, as the title states, we have a 15 month old boy at home and we are renting a top floor unit of a 3 floor condo complex. It also has hardwood floors. In hindsight, a first floor unit may have been better but as first time renters, we weren't sure if we wanted to take a chance with noisy neighbors upstairs disturbing our boy's naps and didn't want carpet because we thought he would make a mess everywhere. Anyhow...My wife is a stay at home mom and we've received complaints from the neighbor below us that our toddler is too loud whenever he runs. As you can imagine, he runs just like any other 15 month old, which jars the floor. We haven't been successful in being able to make him not run when inside the house. Whenever we want it to be quiet, we'll do a quiet activity with him or we'll just carry him around, but that gets tiring and if we need to do something that requires 2 hands, we have no choice but to put him down. Sometimes he'll be fine and walk around but randomly he'll just start running. We can't keep him confined or be right next to him 24/7. We also do not allow him to watch TV, which I'm sure could help, but we choose not to for now.Our downstairs neighbor works from home, so if my wife stays home, he gets quite frustrated and pounds on the ceiling. Our baby sleeps from 7-8pm to 6-7am. When he wakes up, we try to keep it quiet until 9am, which is pretty difficult in and of itself. My wife has tried to accommodate him by leaving the house in the morning and taking him to the park, mall, etc, sometimes staying out all day, but he just wants the noise to stop completely. If it's raining or my wife's sick and cannot go out, what are we supposed to do? We have rugs and mats down to try to help the sound deadening, but it doesn't seem to be helping.I've tried talking to him about the situation and he said he understands that it's not the kid's fault. He continued to say kids have energy, which is great, and need to run around, but not inside the house. It's not the kid's fault, but it comes down to the parents and their parenting, which is indirectly saying that we were bad parents. I told him it's just not possible to teach a 15 month old to stop running. He said that even though he doesn't have kids, he's talked to other people with kids and his parents and they reassured him that a 15 month old can be taught.Is it true? Can a 15 month old baby be taught something like that? I personally believe he either has no idea what he's talking about or he never disclosed the age of our kid and just said "toddler". Either way, I just want to make sure. Any advice/suggestions is appreciated.Thanks. via /r/Parenting http://ift.tt/2eNea4c
