Our biggest problem with the listing is the location. The apartment is not meant for tourists. We always felt that we were stared at and scorned everytime we were in or around the apartment. We did not feel safe in the area. We were told not to make too much noise in the apartment because the lady downstairs was a light sleeper (O.O). That was difficult as we were a bunch of tourist who were trying to enjoy our holiday.
This apartment is not wheelchair friendly as there are some steps that you have to take before reaching the elevator. The apartment is terribly small, and to think that it allows up to five people in the apartment (smh). The four of us were cramped in that apartment and was always bumping against one another. Oh and it's an apartment. Not a condo as it says in the listing. Be sure to bring your own towel even if the listing says that it provides towel. The towels provided were small, probably meant for kids. The toilet is a size of a wardrobe. You could barely move around in the shower, let alone do your business. Also, the dryer didn't work.
The host, Mr. Tam, was super friendly and helpful though. On our first day, he gave us a map of Mong Kok and told us all the places worth visiting. A light in the apartment went out and he came by to repair. The kitchen supplies were complete so if you plan to cook, all you need are the ingredients.
All in all, if you want to come to Hong Kong, book a hotel rather than a B&B.
