I think 5 nights in Jiwo is on the edge of too many for me. 3-4 sounds more sensible for both doing quite a few of activities but also getting a sense of place and relaxing.

This is not Angkor where you can literally visit for 5 days and still only see a fraction and Jiwo in itself is not a “resort-y” type place. But that’s just for me and others may feel differently.

I think the place that immediately springs to mind, though not necessarily as polished in terms of service as Kila, is Nihi Sumba - though you’d still have to connect to Bali.
