My friend and I had planned to arrive at the place in the middle of the night. Hau Kuen provided detailed instructions about everything to make sure we will get from the airport to the room safely and without fuss, and thanks to that, we did.
We were told that there would be no one at the reception that night, but there was a polite young lady who greeted us, checked us in, and introduced us to the room. At 1 AM.
The building was decades old, but the lift works fine, and once you got inside the place it's all clean and bright.
The room is small, as you'd expect in a densely populated city such as Hong Kong for this price. However, it's situated in Mong Kok, close to the MTR station, right at the centre of the shopping scene, and there are several fantastic restaurants nearby, too. What I got was a nice little room with A/C, hot shower, and a cosy bed to rest my exhausted self each night. The Wi-Fi in our room was very slow, though, but some other reviewers said theirs were speedy, so we might just got unlucky with it. I bought a SIM card anyway, so that wasn't a big deal at all.
We never got a chance to meet Hau Kuen during our 4-night stay, but there were some nice people at the reception almost all the time, and that gave me a peace of mind somehow.
