I initially booked Kevin's place to work remotely from for a month and enjoyed it so much I decided to extend for a couple weeks longer (and would have done longer if there wasn't another guest coming in).
Space: The space is technically a studio but I would consider it closer to a one bedroom in size and setup. When you enter you are in a large living room/kitchen area. The back part of the space, divided by a curtain, is a bedroom with a dedicated workspace and a bathroom. The desk is comfortable to work at, WiFi is fast, and it is ideal for working remotely from. The entire suite is well decorated with nice furniture and fixtures for an Air BnB. Kitchen is well stocked with everything you need to cook and prepare meals to save money if you want to do that. Outside is a nice seating area and an electric grill that is great for cooking/entertaining for two. There is also a washer/dryer outside. There is an outdoor shower which was ideal for me washing off beach and dive gear outside. There is also a collection of beach toys/chairs etc to use. If I have one complaint is that sometimes I struggled to get the TV to connect to WiFi to watch Netflix/stream stuff (although to reiterate - the WiFi itself was reliable and high speed for all my devices the entire time).
Location: Great central location for Oahu. The neighborhood is on top of a hill overlooking the ocean and you have a great view as soon as you round the corner right outside the house. I recommend you have a car if you're staying here but depending on your style that might not be necessary (I was doing a-lot of diving and snorkelling so needed a vehicle to carry gear around - would have been much less convenient via ride share). You can be in Waikiki within 15-20 minutes and the location is an easy jumping off point to head east to Hawaii Kai or west to get over the mountains. The neighborhood is very safe and walkable with lots of good places to run nearby. There is a great farmer's market every Saturday at the community college about a 10 minute walk away. There is a small grocery called Fort Rutger Market within easy walking distance with easy Hawaiian/Filipino/Poke style plate meals. The Kaimuki area, with lots of restaurants, is also a 15 minute walk away. There are multiple grocery stores and an entire mall a little farther away. The Diamondhead "trailhead" is 20 minutes away - definitely get there early if you don't want to be in a crowd of people though.
Host: Kevin was super friendly and always responsive. He lives in the adjacent house and very quickly responded to anything I asked him about. Would happily stay at this place or another one he hosted again.
Summary: Great for a solo traveller or a couple - especially if you're working remotely because of dedicated workspace and fast WiFi. Great value and would book again. Although you can get by without a car I recommend having one if you're going to stay here.
