I stayed at Koma's place for 2 nights. If you're traveling with backpacks or small luggages, you'll be happier than me. We had 4 luggages and technically there are not enough space to open all of our luggages. But it's really in front of the subway exit(Z4), sparkly clean and quite at night so you can sleep very well.
Overall, it was very pleasant experience in Taipei and I'm so happy that I booked this room for us. It totally worth the penny. I'd love to stay there again.
