I HIGHEST-LY recommend Lyna's apartment. You can expect:
1. An easy arrival. The apartment building is on Nathan Road, right next to Tsim Sha Tsui station. Take the train and a shuttle, or do what I did and take bus A21 straight from the airport to TST, stop 13.
2. A convenient location. Shops right outside, a 7/11 around the corner for water and snacks, the mall and the ferry to Hong King side a short walk away, restaurants and cafes all around.
3. A professional host. Lyna sends the most detailed instructions on how to get to her apartment and how to find the keycard, in 3 different languages plus a video walkthrough! I have to admit, there was a bump in my check-in but I messaged Lyna about it and she fixed it immediately. Very reassuring to know that if anything goes wrong (because not all travel is perfect), that your host is so responsive and will take prompt action to fix things.
4. An apartment that looks exactly like the photos!! We all held our breath when we opened the door, wondering if we'd get what we were expecting, and we were so excited to see that it was even better. We loved the layout and the decor.
