First of all, Jack is a perfect host, he is always helpful no matter what I needed and replies very quickly.
I stayed at this room for two months and it was perfectly fine for one person. The room is small but clean, a mini fridge would make it perfect. The location is super convenient, right next to the mtr station and many busses stop in front of the building. The air con sometimes smells funny but it fades after some time. Sadly there was some other guest smoking inside the hotel room which I could smell. Other than that, the stay was nice and I would book Jack's place again.
