We had a wonderful stay in Kula! There are breathtaking views of both sides of the island from the patio, and the house is perfectly located for exploring the Haleakala summit. The apartment is large and comfy, and the hot tub was a real treat!
Pamela was extremely helpful as well - make sure to follow her suggestions! In particular, you can drive the South side of the road "from" Hana with a normal compact car, and it's one of the most amazing places on the island (and there are many). She even gave us coats for enjoying the sunset from the top of the volcano!
We are glad we split our vacation 50-50 between the beach and the upcountry, and we would definitely come back!
