That penthouse is beautiful, love the marble floors and bathroom designs.
The kitchen screams 2007-ish renovation, but is perfectly nice. Funny how a million year old stone can look 15 years out of date, but about 6 colors of granite got way overused during the bubble.
I think the current trendy solid white quartz looks like an apple store or biotech clean room and will age badly as a matter of style.
If I had to do a reno I’d use forest green countertops and classic colors of marble and travertine for bathrooms. Travertine looks amazing as flooring but isn’t strong enough and requires a lot of small patching. It is great on walls however.
