I stayed at the apartment long term after arriving in Switzerland. It is in a very good condition, fully equipped with everything one needs at a daily basis. The overall condition of the apartment and the building is very good.
I used the WiFi only a few times but I had trouble connecting to my VPN and video calls very a little shaky, even though the speed of the connection is outstanding. I quickly changed to using an unlimited mobile data plan.
The mattress is a little firm for my taste - but that is a very personal opinion.
