This is a spectacular location first off. Our favorite tea spot, Matcha Cafe Maiko, is just down the corner. It's two blocks from a large shopping center that has Island Coffee, which opens at 6am. So there's lots of food options, even ones open early. It's a short walk to the beach. Across the street from Maui Brewing Company is the closest public access to the beach. Maybe a 5 minute walk total?
Ching is an amazing host. She responded to my questions very fast, and provided a ton of amenities in the condo. If you forget toothpaste, masks, shampoo, conditioner, hand sanitiser, etc she has little packs for you in the closet. If you're sensitive to noise, this may not be the best location because there is live music around 7pm each night. I just used a white noise machine app on my phone and it was fine, but if you're used to no noise at night, Waikiki will be a little loud. This is a great spot and a great deal!
