This has got to be the most unique place I've stayed at to date. It really is like living in a museum, and I love museums so for me it was perfect! It is spacious and good for solo travellers or couples, clean, the location is great with easy access to public transportation, and overall it is perfectly cozy especially during a pandemic when all shops, bars, cafes, restaurants and museums are closed. Mario is a wonderful host who was always responsive and thoughtful, he has clearly put a lot of effort into making one's stay as comfortable and enjoyable as possible. If you are into art (particularly Picasso), books, collectables, or if you're simply looking for a place that is close enough to central but away from all the commotion, then I would highly recommend this place. I have spent three weeks there, but honestly the days flew by very quickly and I found myself wishing i could stay longer. That being said, I would definitely book it again in the future whenever I am back in Zürich.
