We stayed here for 4 nights. There were three of us. Shanshan was fantastic, responded promptly and answered all our questions before we arrived and was easily contactable during our stay.
The place was a good size for 3 people (with one person sleeping on the couch) but may feel more crowded if more people than that. It is an excellent location, safe and secure. The metro is just down the road and Hong Kong metro is excellent (but taxis are relatively cheap as well).
I would stay there again if I return to Hong Kong.
