This is a great place to stay and work remotely. You get a small private room. Shared bathroom and kitchen. There is no heat or AC, but the weather is perfect, so you don't need it. You get a fan in your room. All good. Most of the guests are late-20's and mid-30's guys. They're all working remotely, so they get up early, work, and go to bed by 10pm. No partying retards. It a good vibe.
All doors have key-pad locks. Everything is self serve, no frills, and it works. You can park your car on the street, in the sketch neighborhood across the street, and should be fine. Bus and good restaurants are a block away.
If you're in your 30's and want to make new friends, live cheap, and go on adventures, STAY HERE. If you have kids or old people in your group, stay in Waikiki, and pay more for comfort.
I would stay here again 100%
