I have stayed in dozens of hotels in Laos from tiny family guesthouses to big fancy properties. There is something VERY wrong with this one. I strongly recommend against staying here.
This was a business trip, with two colleagues. A week into my two-week stay we were asked -- or more accurately, told -- to move from our double deluxe rooms to twin rooms, because a whole load of Lao government officials had checked in, and there weren't enough good rooms for them all. We were not offered a discount or any other consideration. They told me I had to be ready to move at 9am. When I was, they weren't (my new room wasn't clean). I had a meeting, so told them I would return at noon to move. Instead of waiting, they packed up my room and moved everything, leaving it on my new tiny bed in a heap.
Two nights before checkout, I returned from a 14-hour workday at 9pm, and the front desk clerks breathlessly told me in broken English that the bill had to be paid "right now", because it was very high, and "we don't know you". It took 20 minutes of my translator talking to them, and a phone call to my Thai assistant, to clarify that the bill would be settled at check-out, which they agreed to. Two hours later when I was asleep, my bedside phone rang and I was asked to come downstairs, where i was confronted by the owner, a middle-aged woman who spoke no English. I realized that I wouldn't get any rest until she was paid, so I just handed them my credit card and they ran it. During this entire time she had the bill in her hand -- it wasn't until after they had run the card that I realized she had included someone else's room on our bill, and had billed us LAK250,000 (around USD $30) for damaged sheets. When we asked to see the sheets that were damaged, they said no.
Rather than deal with their confusion and rudeness any further, we found the other guest in the hotel and he kindly agreed to pay us back in cash. I was later informed that when he checked out, they demanded he pay for the nights they had already billed us for -- luckily I had provided him with a copy of the receipt so he just paid the remaining nights. Sure enough, he was accosted on his way out by the same middle-aged woman, who demanded to check his receipts again.
Other issues at this hotel -- such as no hot water for 14 days, no English-speaking staff at all, repeated unexplained requests to recheck our hotel keys, and perpetually non-working wifi -- would have been overlooked had it not been for this incredibly unpleasant experience. Bookkeeping errors happen, but there is no excuse for such rude and pushy behavior toward guests. I predict that Laos' rapidly-growing tourist industry will soon leave this woman and her poorly trained staff in the dust.
