Tamsen's place was perfect for our vacation. It was very cozy and very clean. Plenty of windows to let the sunlight in during the day and heavy duty curtains (almost blackout) that block out light very well. The bed was very comfortable. The AC works very well. The kitchen has everything you need if you want to cook. We ate out the whole time so didn't do any cooking, but used the cutting board and knife to cut some fruits which were very well kept. The washing machine and dryer that's available also came in handy as we were midway through our trip in the Big Island and were running low on clean clothes.
It's only about 10 mins drive to Ali'i Drive where you can find lots of restaurants and bars. Her description was accurate and instructions were perfect. Please follow her driving instruction very closely as the driveway is around the bend of the road. If you don't slow down when you're near her place you will not have enough time to brake and turn. There is a guaranteed parking spot.
She also had beach umbrellas and chairs available for us to use, which came in handy when we made our way to Hapuna beach (about 40 mins drive).
She was very quick to respond whenever I had any question.
Overall, perfect 5/5. Great location. Very comfortable. Clean. Would definitely try and book her place again when I return to to the Big Island.
