This is an excellent find amidst the bustling Ximen district area - affordable, highly accessible, with beautiful amenities, and only a ~5 min walk from Ximen Station.
As others have mentioned, the bathroom only has a glass door without a lock. You could utilize the opaque curtain provided for privacy, however. Group guests should take this into consideration.
We had a great stay! I will recommend this/rebook my stay when I come back to Taipei!
