I tried four spas. My best experience was with Hogan at Mudan Spa (https://www.muddan.com/) - I actually felt terrible because I had hella jet lag and fell asleep and missed the masseur the first night, so I arranged with them to make it up to him and he came back the next day. Was an awesome experience, highly recommend if you are a top 😛
Second favorite was Meiji with O2 Spa (https://www.otwospa.com/),such a genuinely nice and cute guy and the better massage of the bunch. Enjoyable ending
My only negative experience of the four was with SSB Spa (https://www.ssbspa.com.tw/), but honestly the masseur was super new and I think that was the issue. Was still sorta enjoyable, but not worth repeating.
Can't wait to go back to Taipei.
