Considering the low price paid for the accommodation, it is understandable that certain compromises in service quality may exist. While the room was clean, the issues with amenities, toilet floor drain overflow, unclear directions, difficulties in accessing the building, and problems with the room key were notable drawbacks.
In conclusion, the unit (no. 901) @ Hong Kong Mansion Causeway Bay provided an affordable stay. However, the cluttered corridor and unclear signage at reception (Pheonix Mansion), challenges with accessing the building, malfunctioning amenities, and issues with the room key at Hong Kong Mansion detracted from the overall experience. Considering the price, it's important to keep expectations in check.
