Clean room, helpful host (especially when giving directions), and great location.
The only word of caution - especially to other solo travelers - research the area that this is in. It is in a high-traffic area, so it might be a little intimidating at first. Just follow May's instructions for getting to the place, and you shouldn't be lost at all.
Overall a very good stay. Definitely got a taste of the grittier side of Hong Kong in Tsim Sha Tsui.
