@Robin176 The first thing do to is to contact the host where you would like to stay in singapore. If someone is listing his/her property on Airbnb it means that booking is still possible even if it is illegal by their law. It isnt your problem to worry about this as the host takes all responsibilities. Ask the hosts if it is safe to book their property without getting any problem from their local authorities and you can also check the review left by other guests who recently stayed at those properties. If you want to safe some cash and get a real home in Singapore book on Airbnb. Good luck!!!
