We have stayed at the Waikiki Banyan many times, via different providers, this our first AirBnB - so the facilities were exactly as expected for us.
I probably didn't spot that there was no sea view due to being behind adjacent tower, my fault for not scrutinizing photos.
I was surprised by no toilet door (off its runners) and a curtain instead, could've been embarrassing if we had been travelling with another couple, not our young kids. And the inter-room slider was also off its rollers, another problem when trying to quieten room with kids.
The aircon was exceptionally noisey (compared to our 5+ other times at same condos) - to the point we turned it off when trying to sleep, watch tv, or even talk to one another. It also struggled to keep up on the hottest days, but was ok on the milder days.
Otherwise we will be back to the Banyan again, and will put Rina's on our list of options. We love the location, the ease of use, the kitchen facility and the privacy/quietness. Its no 4 star resort but easy DiY accommodation.
