Honest review and a few things you should consider.
1. Every host has the right to make their own rules, and in particular, beware that you will be in a hotel-like place, except you will need to wash your own towels. Its different than a hotel where you can request new towels and do a little exchange, but not so here. There is a laundry in the hotel, but usually its very busy and all machines are being used. You will need to buy your own detergent. Again, every host can make their own rules, which is fine, but if you want to go to Hawaii and spend your evenings doing laundry, that's fine. Not an issue if you're staying for a few days, but we stayed for 10 days and needed a bit of refreshing midway through vacation.
2. Sofa bed is very uncomfortable. If you do need to use it, you will feel every wire and every spring underneath you. We've learned if you don't move at night, then you can fall asleep and you'll be just fine. Lol. But yes, just be weary that its a bit of an outdated sofa, and if you're ok with that, you'll manage.
3. Location is pretty great. Walking distance to Waikiki and the beach. There's also shops and food near by. Can't complain here.
4. If you want tea/coffee, bring your own. They do have a coffee maker/kettle/cups you can use to prepare the tea/coffee.
5. Only a small amount of shampoo was provided, no conditioner. We had 4 guests and we got 4 of those small hotel sample shampoos. Again, this isn't an issue and the host is not obligated to serve us like a hotel, so just bring your own shampoo/conditioner and don't rely on there being some in the airbnb as you cannot go to the front desk to request more if you run out.
