Sophia's place in Beitou is fantastic -- beautiful and comfortable. It's in one of the greenest areas of the city, surrounded by hot springs, and the hot spring bath in the flat is lovely, and has a view of the city. To see Taipei itself, you just have to ride 30 or 40 minutes on the metro, but it's worth it to stay in such a nice neighbourhood. Sophia was also very helpful, we didn't see her at all during our stay, but she was always available by phone in case of any problems. The building itself is a welcoming place, with friendly staff. I can't recommend this apartment enough.
