Excellent property, excellent host. It's an old beautiful villa in probably one of the wealthiest parts of Zurich.
Pros: Beautiful garden, lake view, well kept villa and room, tram station is nearby, elite neighborhood of Zurich. Host is gracious and may furnish various snacks and items for breakfast.
Things you should be aware of: It's in the suburb and will take you ~20 min to get to city center, check in needs to be coordinated with host and she may have limited time slots (aka it's not like a hotel for check in).
