A welcoming front entry does not need to be grand or elaborate (but it can be). It needs to say you have arrived.
It is not uncommon for me to visit a home for the first time, and to knock on a door that is almost never used by the homeowner or their family members. I am often visiting that house because the homeowner has hopes of fixing that problem.
There are many reasons a home can have multiple confusing entries. The biggest issue is usually poor design, but especially older homes can fall victim to changes in the landscape. Perhaps at some point, the road was moved (that can happen over the course of a century or two) or one of the owners along the line decided to change the landscape or add a garage. Whatever the reason, surprisingly many homes do not welcome their visitors with a clear and attractive front door.
