it is a very outdated hotel to be considered 5 star. felt more like an average 4 star hotel.
I guess its close proximity to Taipei main station gave it its legacy 5 star rating.
also credits to housekeeping for regular daily cleaning of room.
downsides:
double bed was queen size. was really expecting a king size for a 5 star hotel.
headboard above bed was extremely dusty to the touch, and led lights tend to flicker randomly.
bathtub + shower is an outdated concept, small shower area to stand in the bathtub is so uncomfortable.
furnishing generally looks outdated.
worst of all, when all lights are switched off, only a creepy red light (probably from the smoke detector) remains lit right in front of the mirror facing the bed. makes you feel like something gonna jump out from the mirror. horrible experience.
you're better off paying a similar price by finding a 4 star hotel which is 2-3 stops away from Taipei main station, potentially bigger rooms, a more comfortable bed and newer fittings.
