Haitao is one of the nicest host you'll come across. Fast communicator, very friendly, helpful and with a great sense of humor. We booked long term for more than one month. During our booking, he welcomed us to use veggies from his garden, and his wife brought us fruits from her sister's farm in China. There are some more long-term people staying there, which were also extremely friendly and helpful in any information we needed.
Our booking was shortened due to changes in our room condition which we were caused by an unexpected shower problem, which Haitao was working on. Haitao was very understanding of our urgency to cancel the booking.
For those who like it super posh, this is a humble place. It is quiet, safe and clean and reasonably priced. There is a shop right around the corner, where you can buy from power adapters to quite a few things for last min cooking.
If you need to shop, do it early. Mascot is a very quiet area where pretty much all the shops shut at 7 pm. Mascot train station is 15 min walk. There are few buses going into town from Mascot, but they are very slow and with terribly disjointed connections. Keep in mind, in most places, Sydney public transport is amongst the worst in the world, so if you need to go anywhere, best is to Uber it, walk or get a bicycle.
Overall, we recommend staying at Haitao's if you want to save money and it is 30 min walk from the Airport.
