I was here for one day due to my 24 hour layover. Raj, the host was very helpful and ready to help me with every question I have in mind.
The building where the hotel was were very easy to find and very central. I took bus A21 from the airport and it stopped right in front of the hostel building.
The room was clean and the bed is actually pretty big for me atleast or probably bigger than any other hostel around HK. I would recommend a bottom bed because you'll have more privacy from the curtain.
The toilet is pretty much a HK standard but clean and it have hot and cold water.
The check in was smooth and eventho Raj is not around all the time, he's actually provide a no. and a landline telephone for us to contact him.
Lastly, to get back to the airport, I took A21 bus from the bus stand that is pretty only 3 minutes away from the building on the other side of the road. (right opposite Miramall, look for a red pole with A21/A22 sign on it)
I'll stay at Atlas again if I ever been in HK again. Thanks Raj.
