Great location, clean, convenient and much better (and cheaper) than a hotel for a week's working trip. Walkable to the main train station (Cornavin) and transport links, as well as UN/international venues. Supermarkets and restaurants close by. Also nice to be a short walk from the park and lake for a morning run. Useful to have a desk to work at in the apartment and never any issues with the wifi. Very responsive host.
My only comment is that (unlike some Airbnbs I've stayed at recently in other European cities), somebody obviously lives here. So there is not much space to unpack beyond a few hangers in a full closet. If you are good with that, then this is an excellent choice!
