We stayed in Dan's place for 2 weeks Jan-Feb 2020. It was spectacular in many ways. The view of the ocean from the apartment and the pool deck was gorgeous. On 3 occasions we saw whales going by. Nothing better than whale watching with your cup of morning coffee. The pool and hot tub were wonderful and we sat in the hot tub and watched the ocean waves crash on the volcanic rock cliffs. The pool is cool-best suited for Canadians or cold water swimmers. Perhaps what we loved most about this rental was the sense of community that we felt from everyone around. Folks are very friendly and say hello as they walk on the lava cliff walks. There are not many tourists on the east of Hawaii Island so this added to the sense of being part of a community. There is lots to do in the area and Dan is a wealth of information about markets, Volcano Park etc. There are no real beaches to speak of so you will be disappointed if you come for the swimming. Lots of hiking along the seaside lava cliffs.
The only challenge was the kitchen. The apartment has a small kitchenette and the outdoor kitchen has a BBQ and a conduction burner. I did manage to cook full meals outside but it takes some organizing to get everything outside and ready to go. I suspect most people eat out but our habit is to at least cook dinner. The good news is that it is always warm so no standing out in the snow or freezing rain. Overall a memorable experience in this apartment.
