I have stayed at Demian's place during the peak of the corona virus in Zurich for 4 months and I could not have felt more safe at his place. He kept me updated whenever there were any updates regarding the situation and helped me out in every way possible.
The communication was great, he replied almost instantly to all of my inquiries so I never faced any issues.
Also the location of the apartment is amazing, it is very central and you have all the basic stuff you might need (supermarkets/pharmacies/restaurant) within 2-5 minute walking distance and had a train station right in front of the building which was very convenient.
Demian was not there when I checked in on the first day, but his friend was there and he was very hospitable and helped me around the place.
The place is exactly as described and I definitely would recommend it to anyone who needs to stay in Zurich whether long term or short term.
Thanks Demian for having me!
