It was easy enough finding our way there. The google maps link in email sent us to the wrong address but once we figured that out and updated it with the correct house number there was plenty of signage and with the map provided it was super easy to find and park. Parking is on a hill up a long driveway which is slightly tricky but not overly hard. We had a back-up cam in our rental vehicle, but had we not had that it would have been much harder. The stairs to the house are easy enough and there is a house for spraying off your feet/shoes along the way which was super helpful after walking back from the beach. The view from the room is porch at the top is beautiful and worth the stairs. It's in a very woodsy area so there were tons of little geckos around the outside.
The interior is also super nice, all the little geckos were trying to break in. There is plenty of room for a large group, it was very spacious for our group of four. It was nice have the closet with beach items (towels, snorkels, chairs), we put them to good use! The only warning with bigger groups is keep in mind there is only one bathroom, so there was often a line in the morning. It's decent size bathroom though, so multiple people could use it to get ready.
The only "negative" is the lack of AC in the main living space, granted the information is up front about this. There are individual units for the bedrooms, so sleeping was no problem but it got pretty stuffy in the main area. They had two fans but one of them didn't seem to work very well. We opened the windows at night and that helped some, but during the day we mostly hung out in the bedrooms.
This house it pretty close to Haleiwa for dining and shopping, but during evening hours the 7 mile drive can take 30-40 minutes. It's a pretty drive and we didn't mind, but we were shocked at how it can take 15 minutes one hour then 40 the next. Getting back from Haleiwa was always faster then driving there.
Over-all it was a great experience and we would definitely stay here again!
