It`s a lot for reasons to stay at Maylyn`s, but the best ones are probably: #1 Great value rooms in a beautiful garden, #2 Excellent food (try the Lao chicken with mint and chilli !!!), and #3 friendly and helpful staff.
Apart from that the place is excellent placed just outside of Vang Vieng centrum, away from all the loud music and drunk tubers. Maylyn is run by a friendly Lao/Welsh couple whare the Lao woman (Wan) makes you great food while you drink Beer Lao with her husband Joe and Uncle Tom. Thay will both tell you great storys, jokes and what to do in Vang Vieng and its surroundings.
Tom, the Irish guy next door can take you on bike tours on his brand new motorcycles at reasonable prices.
I had a great time, hope to see you guys again!
