1. suspected bed bugs.
lived for 3 nights, got itchy reddish bumps all over my and my friend's legs and arms on 2nd day. at first I though it's mosquito bites, so I requested liquid electric mosquito repellent, but it did not work. more and more bumps were found on legs on 3rd day, google suggested it's bed bug bites. in addition, other hotels in surrounding areas of Taipei were claimed to have bed bugs since Dec 2923. I did not look into this any more as I left Taipei in early morning.
2. sound proof is horrible. can hear outside ppl talking, walking in midnight and dawn, severely affected my sleep.
3. location is good, price is much cheaper than other hotels in same area, very friendly and helpful staff, room looks new and well-equipped. but all these do not matter.
