What about for 'un ambiente sano'?
Talking about a house and considering, damp, dry rot, ventilation and light, I've never heard 'healthy' but good condition but I don't feel this is enough. Does anybody have any ideas?
That's easier and quite straightforward. A healthy lifestyle. A genuine life can mean that the person is living a lie: I became a lawyer because my parents wanted me to follow in my father's footsteps. I really wanted to become a sailor and live at sea. After ten years I decided to leave law and live on an island and have my own private boat - a genuine life! (I wish!)
