Buoy guesthouse is in Sangkhom. Its well signed at the street. Also the busdriver knows the place. There are 5 bungalows over a wooden bridge along the Mekong. They are making a new footpath before the bungalows to walk along the Mekong. These bungalows are spartan. Double beds with a moskito net and they have a shower. There are also 4 bungalows in the garden. Bungalow nr 1 was very humid.( july) . We changed to nr 4 and this was very big and we liked it a lot for the 400 baht. It has a good aircon and good shower. The " restaurant" serves good food. Drinks you can get by yourself.
The owner,a very friendly and always singing and laughing lady, has to do a lot of work. Her husband passed away four months ago. We hope she gets a lots of guests so she ears the money to do some maintanance. Wifi is available in the restaurant.
