Blanca and Chris's place was located in a really convenient area - it was a really close and easy walk (~10min) from the Zurich main station. There's also a lot of places to shop and eat just in that area, and it's very quiet at night. The view from the window is great as well.
Chris was really helpful; he met us on the first day and walked us up to their place. He and Blanca left a lot of travel guides for us, and he offered to give us tips of popular restaurants and things to do in the area.
Overall, we liked our stay! We would definitely come back to visit.
