Dan&Button have a great place here. It is spacious and of great value considering the cost of rental in Taipei. The three rooms each have got soft and comfortable queen-sized beds.
Its location is immaculate, within walking distance from Taipei Main Station if you're happy to walk while the weather is nice. Otherwise, being one stop away does not hurt at all. It is just literally a stone's throw away from Shandao Temple MRT station.
