Is this a no no for kitchen tile in rental (travertine)?

[John Collins]

It's a travertine with a great feel and the only tile that matches the existing set up close to the price point. stone look Porcelain feels cheap IN THIS instance and clearly printed on. So to landlords out there... do any of you have problems with travertine over time (indoors, particularily in a kitchen area)? Obviously it will be sealed, but with the gaps and the fact that it's not filled in, it makes things harder to clean. Would you just be safe and go with the porcelain... it's a nicer home. Do renters comment on this?
