Sophia's place has a great location - right along the thermal valley of Beitou, close to the hot springs and museums, shopping, MTR, etc. We chose her place because it was near the public hot springs, but we ended up not using them because of the hot springs and pool that were offered in her building. Bring a bathing cap if you intend to swim.
The apartment is comfortable and has a nice view. You can cook or eat out at the many restaurants nearby.
Sophia is a gracious host. She responds quickly to questions and is an interesting and warm person.
