The location of the guest house itselft isn't that bad but I didn't like the staff's attitude. We were staying there for the time of Sonkran festival which means that many rooms in the town were occupied already. We decided to check on several guest houses if they have vacancy for the most busiest dates. When we came to Muonglao Guesthouse and asked about the vacancy for 6 nights (also for the period of Sonkran) they assured us with smiles on their faces that they have a room available. Great! When we checked in the next day, they told us, that we can only stay 4 nights as they already have a booking for a big group, booked a long time ago. OK, thanks for not telling us that yesterday!
They also told us the price for the night and said AC is in the room, too. Upon check in we realised they "forgot" to mention that AC is not included in the room price.
We also wanted to do laundry, which they advertise on a poster infront of the GH. Regular laundry - 10.000 KIP/kg, express - 15.000 KIP/kg. I asked for a regular but when I pickud up the clothes they charged me 15,000 KIP/kg. When I complaind they were just smiling and pretending they didn't understand me. I showed him their a poster with the price and the guy just torn it off and said it's not the right price. If I knew that I would do laundry anywhere else as they all have a price 10.000 KIP/kg.
If wi-fi is important to you, don't stay here, it's super slow - when it works, that is. The mattress was horrible as well.
At the end we were happy that we had to go out for the last 2 nights and we find a really nice GH a few meters down the road (pass gass station and turn left on the mini road where you wil find Phontida GH).
