This was the most affordable AirBnB I could find in May of 2022 that was relatively close to Waikiki at $83/night, including all fees. It's about a 45-minute walk to the center of Waikiki, where all the shops are at (Royal Hawaiian Center and Waikiki Beach). It's located in a very convenient location: there's a 7-11, a Daiso, and a Zippy's (Hawaiian diner) across the street. This host also provides overnight parking at a very affordable rate of $10/night (even cheaper if 7+ days parked), compared to the luxury hotels charging $55/night for overnight car parking. This is definitely not a 5-star hotel, so don't expect luxurious comfy beds, breakfast, or amenities. For it's price point, it's cheaper than the rest of Waikiki.
The room was clean upon checking in. The twin-sized bed isn't that comfy, the mattress is a bit stiff, and the pillow wasn't the best--pillow seemed to be of the cheapest quality, but you get what you pay for. The hotels' couches (visited a friend's hotel once during my vacation here in Hawaii) were more comfortable than the bed itself, unfortunately. Most importantly, there is no Air Conditioning in the room! There are two portable fans in the room (so you can move the fan on the bedside table blowing at you, if you wanted to); both were quite dusty and had big dustballs in them. On hot days, the room does warm up. Again, you get what you pay for.
The host does provide 1 bath towel; no toothbrush, shower loofahs, nor slippers; you will need to buy those yourself. Daiso, across the street you can purchase those for cheap. However, there is sunblock, shampoo and body wash that other traveler purchased and left in the bathroom for public use (I also purchased some new shampoo and left it for everyone, as you can't bring it to the airport anyway). The bathroom is decent, and can certainly use an upgrade (a Japanese bidet would be absolutely wonderful and wouldn't break the bank; a removable handheld showerhead would be nice) and a bit of extra cleaning. There's also no hairdryer in the public bathroom, as I think the reason is the added costs of electricity. I spotted a few couples in the bathroom scurrying around at night though!! Yikes.
Check-in and check-out were as smooth as butter. Excellent customer service-- the host will try to accommodate to all your needs. I needed an extra towel and was given one, at no extra charge, the next day. I even borrowed a charging plug because I forgot to bring one.
Overall, this place was the most affordable AirBnB I could find at the time of May 2022 and was sufficient in my stay and the host was very nice. Would recommend for the solo traveler.
