The outdoor bath and the in-room bath. The rooms are big, clean and comfortable.
The hourly bus shuttle service is too long to wait. So we took taxi most of the time.

The shuttle bus was great on the weekends! The breakfast was pretty good too, but the best part is the private hot springs bath
I wish the shuttle bus had more times in the morning and evening during the weekdays. I also wish the location wasn't up a steep hill

We had a wonderful time at the Gaia Hotel. Everything was clean and room service gave us new fruit every day. Darren was extremely helpful and went out of his way to make our experience phenomenal.

Facilities are great, well maintained. We had hotpot for dinner which was also very delicious. We had some hiccups but Mr Yang, the director in charge walked extra miles to comfort us and shared his views on making the hotel a better place for guests.
Staff, especially frontline ones, are relatively inexperienced, resulting in some failures in service delivery, though attitude was good.

The breakfast, the hotsprings were very good.
The location is on a hill, requires alot of walking.
The amenities did not felt luxurious, the hotspring for men did not had the snow machine as advertised, and they close the outdoor hotspring without announcing anything.
Overall too expensive for the quality you get, specially when comparing to other locations in Beitou.

Worthy of 5* rating. Ms Winnie? Wang brought us tea in the library at check-in, set up the room with shower chair AND toilet seat handles, all without us asking. Had correct # robes and slippers. Everyone there was just friendly, helpful, smiling, and always deferential to grandpa. Owner walked in the front entrance while we were waiting for our taxi at check-out and she asked if we would like water or tea. Seriously, what hotel owner DOES that?? Room was newer, modern, and exceptionally clean, including the hot springs soaking tub. The Beitou hot springs water does not make your fingertips wrinkled. 30 minute muscle relaxation massage was excellent, at 55usd. Overall, stay was pricy, but you absolutely get what you pay for in this case!
It's on a little hill. They have complementary shuttles to the MRT and I believe to town?, but if you want to walk back, it will be a good workout.

The facilities were good. We had dinner at the Japanese restaurant and were satisfied with the food's quality. Complimentary snacks and drinks within the room added to the experience.
The onsen within the room was not completely clean as hair was noted at the edge of the bathtub before first use, although the room had a strong smell of disinfectant. The swimming pool was not open due to cold weather, even though the weather was mild (15c). The restaurant was understaffed as staff were seen attending to the function rooms and left the restaurant unattended at times.

The breakfast was good, especially because it had a pot of drip coffee and a granola like cereal. And I really enjoyed having a Japanese style bath in our room!
I wish the price was a little lower.
