Absolutely recommended! I lived in Tzu Chen's apartment for almost 3 months and it was definitely a pleasant stay. The apartment is located in a very central position, less than 5 minutes walking distance from the Zhongshan Elementary MRT stop (Orange Line) and if you are up for a walk in a green area, the Expo park can be reached on foot in a few minutes. Whatever you need (pharmacy, restaurants, post office, open air market, supermarkets open 24/7, bars, coin laundries, etc.) is at walking distance. The apartment itself is small, as big as a hotel room, but equipped with all the necessary services including bathroom with separated dry and wet areas (which, trust me, it’s not easy to find in Taipei). The price is also fair compared to the other apartments on the platform. The landlady doesn’t speak english but she’s very kind and always ready to help.
One think you should consider is that the mattress of the queensize bed is quite hard so if you have problem with that, please ask the host, I'm sure she'll be happy to help you someway.
