Gordon's place is pretty reasonable for what you pay! For someone who wants to spend the majority of the time in the city, it's quite far out of the way, but it's doable if you don't mind taking the MTR into the city/touristy places everyday. We were there when it was very hot and humid, and the AC was a lifesaver. There's also a really authentic noodle shop and a beautiful temple around the corner!
One big issue that I had was communication. Gordon sent us too many emails -- look, I've stayed with a handful of hosts over the years, in the US and Europe, and they really did communicated everything that was needed in as few emails as possible. Gordon sent us 3-5 emails a day, and I felt like it was partially how the airbnb chat&email system was set up, but also little things like "Hey we flush our toilet papers in Hong Kong, just like in the US (where we came from)" even though he didn't have any paper towel/clean hand towel so we were just using the only kind of paper available to dry our hands (Actually, he didn't have any full roll of toilet papers during our 3 night stay).
He assumed that we were taking the airport express and scheduled our check in time 2 hour after our arrival, even though we never confirmed that with him. So when we took the bus and got there 3 hours later (still before noon, normal check in time), he lectured us like children. No one needed that after a redeye flight, right?
During our last day, he also kept asking for 5 stars (up front) even though we did NOT have a 5 star experience. I felt like we were constantly being watched and lectured electronically. Anyways, this was an honest review. We've had a great time in Hong Kong, but I wish things like these didn't have to come home with us.
