But are there other problems I should be concerned
about.

You seem to be aware of the roughness. This will make it impossible to
keep clean. Are you aware of how porous and spongy travertine is? The
roughness means you will have vegetable material that will leach tannins
and foster mildew growth. This brown and black staining matter will soak
into the stone and stain it permanently. In short, this stone will weather
into a real dingy state, nothing like when it is new. Is this part of the
"Italian" look you are after?
