I've stayed at Innspirit (Tsim Sha Tsui) with my three friends in a Triple room + Extra mattress. The room is super bright and clean, only some little dirty underneath the washbasin but it was definitely ok, no problem with me at all.
The room has towels, a hair-dryer, TV, air conditioner, Wi-Fi and water heater. The microwave, fridge and free cold/hot water at the mini sitting room. Samuel, the owner, is very friendly, polite and helpful. His English is very good. He lent us a Hong Kong tour guide book in Thai language and an umbrella.
Something I would like to note is the hostel is located right behind iSquare mall, Tsim Sha Tsui MRT ext. H. It's in a building that has a wooden sign "Rodeo Drive" in front and located on the 6th floor. This information helps me to find the hostel easier but didn't show up in the hostel Airbnb and official website. So I decided to share this to others.More
