The owners were so nice and helpful, you can query whatever you want to know about the trip.
And the room is clean and big. The view also fabulous, you can enjoy sunrise during the early morning.
The breakfast was simply but good ,you can even taste local snack.

Had a lovely stay at the Waterfront Hotel. The man and woman of the hotel are very, very nice, the views of the balcony over the Mekong are superb and the wifi is good but.....
i booked through them the package for the slow boat to Luang Prabang. Thought it would be easy for me to book via them, but afterwards this was totally not necessary, because would be easyly done by ourselves. Payed around 10 euro above the normal price (doing it by ourselves). After the border with Laos had to wait till other tuk tuks arrived, and got scammed to book a guesthouse, had to wait long time and arrived very late at the boat.
It is very pity the people (who are very nice) of this hotel work together with these people of the scam (though i am not sure they know about these misbehaving)

As other posters have mentioned, it is the owners that make this a great place to stay. What a wonderful and engaging couple.

The room is basic, but the view of the Mekong is amazing. There is breakfast provided and you can eat out on the deck overlooking the river. Lots of restaurants, a small store at the corner, and delicious food stands nearby,

Chiang Khong is tiny but friendly. The owner of one of the bars bought us all welcome drinks.

If you are planning on doing the slow boat down the Mekong, make sure you choose the Day Waterfront as your stopover. The owners gave us clear instructions on the transfer process and saw us off the next morning.
