Christine is very kind and accommodating, and the place is in a great location. It is walkable to the centre of the city (30-40 minutes), the harbour (lake, and river, 15 minutes), and some walking trails overlooking Zurich (10 minutes). A few minutes walk at most to plenty of grocery stores, restaurants, and the like. The tram line comes just outside the door, so it's easy to get anywhere in and around Zurich quickly. Christine has lots of good suggestions of events and places to check out.
If I go back to Zurich, I definitely want to stay at Christine's place again!
