I would recommend you find somewhere else to stay. There are lots of other great looking places around Bondi, including places in Bondi Junction, that I wish we had stayed at. There is really no need to be this close to the beach (which is the only thing going for this place); public transport in this area is great, buses are going all the time from Bondi Junction to Bondi.
I’ve stayed in lots of Air Bnb’s all over the world, even in hostels people don’t behave the way Alejandro and his friends decided to - waking us up at 3:30am and then continuing the noise for another 2+ hours. It’s rude and completely inconsiderate, especially when we paid so much money to stay. The fact that he is now refusing to refund my third night’s stay is appalling. I just would not do that to someone. I’m pretty surprised honestly, I’ve never stayed anywhere that the host was this disrespectful.
The lack of hygiene in the bathroom and kitchen is pretty gross. Human hair on bathroom floor, soap scum caked into the bath/shower, cockroaches on kitchen benches, just disgusting. If you don’t mind that, and decide to stay anyway, I really would recommend you don’t cook anything in the kitchen, and that you wear thongs/flip-flops when having a shower. I also think you could potentially get food poisoning from putting your stuff in the fridge so make sure it is in an airtight container. The smells emanating from the fridge and dishwasher are really foul.
