I'm currently staying at the Madera Hotel in Kowloon, Hong Kong. It's a small boutique hotel with very nice modern rooms and friendly staff.
The Panorama Lounge on the rooftop (29th floor) has spectacular views of the city. In fact, I booked this hotel based on 3 things:
1. the very good reviews/ratings it's received
2. close proximity to the MTR (underground train)
3. the rooftop view :)
