I just polished the floor. It is indeed very nice and it's actually one of the thing that I'm glad that I didn't change it. The stepping feel is so nice, cooling and smooth without tiling grouts. Mine is in very light beige/peachy tone, hence it matches nicely with any colour of interior including wood pieces. However, there are many marble floor in other places are grey in color (light or dark grey). If it is a grey marble, the color selection (including wall color and furniture) must be very careful...otherwise it will easily turns into an aunty's house.... Personally feel that all tones of marble floor must avoid interior wall with green or light blue tone.
About the centre courtyard:
There is a double volume void area in the house which I call it centre courtyard. It's not entirely covered with roof so that it gives a good ventilation to the house. There is my next project to plant a tree there and cover its entire floor area with pebble stones.
