Absolutely filthy. The bedsheet had a stain. The blankets and pillows feel like it has never been washed or changed because it caused allergic reactions to our faces and skin. There was a huge spider on the window beside the bed, which made us have a fear of it crawling on our faces at night during our sleep, so we slept on the sofa. The apartment is also too cold and has insufficient heating. We left after our second night and didn’t complete the entire stay. And the host is inconsiderate and refuses to even give a partial refund even with the knowledge that we have checked out and did not complete our stay. An absolute regret. It made our experience in Zurich a total nightmare.
