The MTR is an 8-10 minute walk from the Pentahotel in Kowloon, though taxis are better for shorter journeys since their starting price is so low.
The entrance is on the ground floor, while individual check-in is one floor up. The lowest floor is used to check in tourist groups. Every evening the entrance was packed with Chinese, Korean and Japanese tour groups waiting to be escorted to their rooms. There was also a pizza bar on the entrance level, which had some fascinating pizzas.
A quick escalator or elevator ride takes you up one level to the main lobby. This area is slightly more calm with spread out seating and a pool table.
