A small house can be taken for 150 USD per month + water + electricity
Here are a wide range of guest houses and hotels.
As usual, throughout Asia always ask ahead show room. Check out the views from the windows, shower room, the toilet, hot water, bed linen and bed itself.
Sometimes there are exceptions, such as Mixay Paradise Location: 17.96544, 102.60482 , where you may do not check the rooms (the rooms are clean), although lots of them with internal windows (windows, opening into the corridor). Therefore specify such things in advance.
You can view prices, book accommodations and read about the pros and cons of various hotel search engines in my review of hotel and apartment reservation systems
In addition, pay for breakfast. For two 1,7 USD = 15 000 LAK ie 0,85 USD = 7 500 LAK per person, a great price !!!
DHavara hotel- a great brand new luxury hotel in the center of Vientiane
As the city is included in the UNESCO World Heritage Site, hotels prices are quite high.
There is an area with relatively low-cost housing. Approximate Location of the area 19.886778,102.139962.
I advise you to come to the city as soon as possible and not with tourists form boats. All tourists in the evening are seeking for accommodation, and when the owners see a lack of space, they automatically turn up their prices. And hard to find housing when you are tired in the evening.
Guest house with a more or less decent decor average purity and good view 9 USD = 80 000 LAK
