The apartment is well-maintained and spacious. Though it is located close to a restaurant, it is still pretty quiet at night. So don't need to worry about being woken up by the noise outside or next-door. (said by someone who is sensitive to noise and usually uses ear plugs for sleep :)
Plus, the location is great. It is only a few min walk from convenient stores, restaurants, shopping area and MRT station. You can travel around Taipei City fairly easily.
More importantly, the building is well-managed with 24 hr security guard at the front door, so I think it is a safe place to stay even for female traveling on their own.
Above all, Maggie is a great host. Very responsive, friendly and always does her best to make you feel at home. Feel free to ask her any questions about your stay and info that will bring more fun to your trip!
