I too am having this issue.
My wife and I along with a 3 year old kid recently moved into a brand new unit. A few weeks in, we were told by a neighbour not to put a doormat outside at the entrance to our unit.
The hallway isnt carpeted like most units which makes it easy for dirt and dust to come into the unit. With rain, or wet floors, it will just make matters worst.
We are a working couple so cleaning the house regularly is a challenge. For hygienic reasons, we do not keep our footwear on within the unit
What I am keen to know is if there is a way for me to stand my ground and leave the doormat at its place. Appreciate your input on this matter.
