The flat is plain and pretty cheap, I think. Not everywhere it‘s very neat&tidy. But for a few nights and such a location (15 Min by tram to the city centre) it is okay, I think. Our room was good.
The host is very friendly, kind and helpful. We got anything that we needed or asked for. Towels should be brought on your own.
Maybe two separate blankets for two people could be a good idea.
The price is not „super cheap“ for young people etc., but everything in Switzerland is much more expensive.
So it was okay.
