Karina’s apartment is in a wonderful location, right in the heart of old town Zurich. She provided me with extra amenities I wouldn’t normally expect like snacks, coffee, water, toiletries etc. She was readily available for any questions or concerns.
The only slight downfall is the noise from bar downstairs, but this is to be expected in city center (also I stayed on Friday/Saturday night so I expect it was louder that usual), and quieted down as soon as bar closed. I would definitely stay at Karina’s place again.
