a lot of people without any relations between them are sharing accommodation here. Let's say , in villa 2 males and 2 females stay (each one in his/her own room) under the same roof.. it is just a Real Estate situation in Qatar - sometimes you grab whatever you can find, not whatever the law is or your preferences are...So just be discrete, and the main thing - do not piss off anybody.. and you will be ok...
question to Oryx .. you said: it depends on your nationality, and then you gave an example of western couple having troubles.. So as I understand if you are westerns you may get in trouble.. and what nationality wouldn't have a problem? .. and by the way how this western couple's issue has been solved? Was it a Happy End?
