We booked 2 rooms for 5 people.
Positive things: Clean, free mini bar (plenty of snacks, coffee, tea, and soft drinks), free breakfast, good in-room WiFi, nice location (5-7 min walk to NTU station, 10-15 min walk to Ximen station), free Video on Demand, helpful staff for booking a car to & from the airport (NTR1,600, one way, for 5 people - reasonable IMO), and we got free room upgrade
Negative things: A little small breakfast space (have to wait a little while before getting seated), not so comfortable pillows
Booking tip: The bulk-bed is not suitable for a person higher than 180cm.
