I had a really nice time at Ken's place. Stayed there for 3 nights. I would recommend this place to budget travelers who will be out most of the day, but needs a convenient, safe, comfortable and clean place to come home to. Most reviews say the room is small, which is a standard in HK. But our room (and the toilet) did not feel cramped at all - unless you're a really big person. We only had handcarries but a trolley or two can still fit in the room. No closet though but there's space to put your clothes, toiletries, etc all over the room. The guesthouse is very convenient location-wise. Everything is walking distance: A21 bus stops from and to airport, MTR Mongkok E1 exit & others, Ladies market and sports goods street, grand plaza, langham place mall. Early in the morning we eat at the congee places around the area for breakfast that elderly locals frequent. Just walk around and you'll def find one. One week before your stay, Ken will send you a FAQs sheet. It has all the info needed about the guesthouse and directions to the place which they have youtube videos of. Wifi was stable and fast. Mongkok is a very busy place with lots of people but the rooms are quiet and high above the busy streets. Security is stationed beside the elevators and monitored with CCTV cameras. Also, the guesthouse has 24 hour front desk. They're called a guesthouse but really functions more like a motel.
