Spent there 3 nights, in room n°5 (350kIDR). The room is nice, white walls, nice bed and a large terrace on the garden, with beautiful view on the forest (seems some guest saw the sea, they maybe had too much Bintang...). The place is clean, even if we had to ask to towel change and if the bathroom cleaning is average (when you are staying few days at least).
The place is quiet with a beautiful garden and mountains view, but anyway you may be waked up at 5 or 6am because of all animals around, and the only road crossing Munduk is not far as well... I guess this will be the same in all Munduk accommodation.
Restaurant menu is limited and meals quality is average, you have better to go outside in some warung or restaurant (see Don Biyu).
Maybe they saw previous guest comment on TA, they gave us the map from another Guesthouse for the treks, it was OK for us - means you can make some beautiful walk around without guide.
Location is great, in the village, not far from the walks start points, from warung, shops, .. (a lot of accommodation are 1 or 2kms above the village)
This is still a good value hotel, but consider to have your meals outside.
