My friend and myself did the 3 nights - 4 days retreat. Delightful.
Accommodation wise, due to hotel unavailability, we stayed in the very spacious and very clean room that Marc & Meng have available near the studio house - and it was perfect. Just needed to wake up 10 mn before the start of the lesson, which is a blessing when you have not so much aptitude to early waking up. The location is great, peaceful, in the middle of the rice fields, with a beautiful day and night sky, and a mere 20 mn bicycle ride to Pantai Cenang.
The food is delicious (Meng is a redoutable cook, I stand up every dinner saying "again, ate too much").
Yoga and meditation classes are great as well. Quite different from the type of yoga we've been used to where we practice, more as an aerobic exercise than anything else - going deeper into the meaning of yoga. Marc & Meng have different styles, both enjoyable and interesting.
Remark : planes from the airport can be heard, but not that many that we felt it was an hindrance to the retreat. A sound to easily incorporate to meditation.
So in a summary, a great stay :-).
