I would 100% recommend staying in Sam's guesthouse! The room is small but has everything you need in it. (shower gel, shampoo, hairdryer, towels, kettle, adaptor) The bed is super comfy and the design of the rooms make you feel like being in a little home.
The communication with Sam via WhatsApp was super fast and easy. He gave very clear information on how to get to the apartment and how to enter the room (even with photo and videos!) In addition to that he is very helpful finding restaurants, doctors, etc. You can basically ask him anything and he helps!
The location very near to Jordan station and the Airport bus is super convenient! Supermarkets, Mc Donald's and Starbucks, as well as other restaurants are in walking distance.
I will definitely book one of Sam's rooms again, when I need accommodation on Hong Kong.
