We rented the two one-bedroom apartments at Pandanus over Christmas 2013. My husband and I were in one apartment and our Sydney transplant daughter was in the other. Great location - apartments were roomy with well-stocked kitchen. The bbq grill was great - we grilled out several nights. Liz was a great help - met us at the airport and was willing to drive us as needed around the island. Also most helpful describing various beach/ hiking/dining options available.
Lord Howe has certain 'quirks' that should be considered before going there. First of all the island is very quiet, no cell phone service and night life ends with dinner service that ends about 9:00 pm. The island is also very hilly- if you don't like walking or riding bikes, transportation is difficult. Apartments will drive you to dinner and the restaurant will return you, but outside of that, you are on you own 2 feet.
Secondly, make dinner arrangements as soon as possible. Restaurants are open only certain nights, and they fill up quickly.
Third, bring some of your own food. We brought 2 dinners - steak and chicken. Also brought several bottles of wine. Food is available and varied on the island (bakery goods especially great) but it can be expensive.
Finally, expect a great time. The water is spectacular. The folks are super nice and Pandanus was a super place to stay.
