Visited the place with my friends and a kid in the month of April 19'. Following were the pros and cons of our stay..
Pros-- Very hospitable staff.Mr Karma arranged vehicles for us and also helped planning the trip.Home made food especially the breakfast spread was very delicious.Mrs.Namgyal was ever helpful.They provided boiled egg every morning for the child.The room had a beautiful view and the washroom had all modern amenities.The decor of the place needs a special mention.A nice garden adorns the place and an outdoor seating area gives an unobstructed view of mountains, clouds and the valley beyond.
Cons:Faced water crisis during our stay. However this might be an exception because while booking never did I come across this crisis in the previous reviews.The road leading to the place was quite elevated hense not advisable for the elderly, sick and also for small children(you might have to carry them which would make the walk even more difficult)
In short the place and our stay was a pleasant one.
