haydee, oh, what a pity. I hope putting it together works.
Stairs covered with natural stone also feel more like a public stairwell to me; I wouldn't want that in the living area, even though it's done stylishly.
I don’t like wood-look tiles either, but if people like them... fine. It’s good that such things exist now.
Tiles throughout the entire floor would be a nightmare for me too. But many people have tiled living rooms, and yes, with underfloor heating it’s not cold on the feet, but cozy is somehow different...
But these are just MY views and no one has to share them
