I just wanted to get some opinions on whether a family with small children in an OKW GV is a good idea. Are the stairs a problem? Both the stairs to get in the front door and the stairs within the unit. Do you need to bring gates to protect toddlers? Just curious whether it is a concern or if I'm overthinking it. The children belong to another family, not mine so I'm not sure what's a problem with strollers, etc. and what's not.
