The interior is looking great.
Some people are just meant to wander, while I did not have the choice of where I grew up or was born, I am part of a family that has had the wanderlust gene. Born in a place that was another country, and then living in so many different places in America and knowing this current location is not nor will be my last. Your niece is in for a lifetime of learning what it means to be her. (gotta go breakfast, will finish later).
This is what I wonder - it does seem to be very much genetic. I know a few families similar to my own, where they are continuously on the move. We don't have to follow the food anymore, we can choose to follow the heart.
It also does not hit every person in the family, I am the only one in mine to live in so many diverse areas, the rest are all still with in 50 miles of where we grew up.
I count your niece among the lucky to have inherited it. It is nice having family that stays in one place or area, always a fall back option for stability, but the urge the need to see different and far away things is strong in the entire family, some just see it through our conversations and letters back home, but the whole family travels with and has a place to visit when one of us hit the road.
