We call it Homestays in Malaysia? Some places like Singapore, they call it Staycation. Well, advantage would be you can charge premium (and still cheaper than hotel), like RM300 - 400 per night for a 3 bedroom condo. BUT you might not rent your unit out on daily basis. Usually all these homestays, they are only occupied over weekends. So, have to take into account on the days when it's vacant. And housekeeping is another cost you have to take into consideration.
One of the websites you can use to advertise your homestay is www.ibilik.my and www.airbnb.com
