I am currently taking some time off work, but usually find myself working as an engineer for software/web companies. I don't drink, I don't smoke, and I have lived with something like 15 housemates/flatmates with whom I've rarely had issues. I love being physically fit, and travelling to exotic locations. I drive a Vespa and have no diet restrictions.
If I'm staying at your place, hopefully my listing gives you assurance that I have a place I respect and will bestow that same respect onto your place.
