Wu's Casita is in a great location, with 101 and the Tonghua night market (通化夜市) both a short walk away. 吳爸爸 is extremely kind and helpful. The building on the older side, like most Taipei residences, but Wei Wei and her father keep it really clean. Only qualm for me was that the rooms seem to lack a little sunlight (one of the rooms has no windows at all).
