* El suelo se ve bien: This is a straightforward and common translation. "Suelo" means floor, "se ve" means "looks," and "bien" means "good."
* El piso se ve bien: This is also very common. "Piso" is another word for floor.
* El suelo está bonito/a: This translates to "the floor is pretty," using "bonito" (masculine) or "bonita" (feminine) depending on whether you're talking about a specific floor that you're picturing as having feminine attributes (like a highly polished wooden floor) or not.
* El piso está bonito/a: Same as above, but using "piso."
* Me gusta cómo se ve el suelo/piso: This translates to "I like how the floor looks," which is a more personal expression.
The best option depends on the context. For a general statement, "El suelo/piso se ve bien" is perfectly adequate. If you want to emphasize the aesthetic appeal, "El suelo/piso está bonito/a" is a better choice.
