There are many fully furnished apartments in Vientiane like the pictures below. It has basically everything you need, and there's even a maid to do all the full cleaning services for you, including your room, dishes and clothing.

Apartments in Vientiane are a convenient choice for those seeking long term accommodation. If you plan to stay for a few weeks, then guest houses and hotels are the best options.

This particular apartment is near the Soradith nightclub so it can be noisy late at night when nightclub goers return home.

It's nice, apart from the toilet and shower area because it's not too spacious, but I'm told that the problem is just with this room.

Rent costs $300 US per month with free water usage.

They only have double size beds, so you'll have to sleep with your roommate.  

Very nice indeed.  Lao Democratic, please do not get a roommate to share your apartment unless a hot Lao chick .  Are the houses and aparments in Vientiane produced by the same builder?  They all looked similar to me (exterior and interior color selections and roofing style for examples).

Lol, wife for foreigners, girlfriend for Laotians.

Unless you're a foreigner who's partial to Lao prison.

True. I think it's funny how the culture is modest, but then you hear about the Hmong who sometimes have multiple wives.

There's a law that says Lao nationals aren't allowed to sleep with foreigners, unless they are they're married.

Foreigner gets a huge fine, and khon Lao maybe goes to jail.

Actually our very own web hosts have a pretty good page about it.
