Karla is the sweetest and most welcoming host! Her appartment is great and feels like home. Definitely big enough for 2, and super well located. I fully recommend you Karla's place!! :) One detail to know before, there is no wifi available. But this is easily solved as there are multiple phone shops close by the appartment and you can buy cheap data options or a USB key with wifi. I did it very easily and it worked smoothly (even on a Sunday) :) Will definitely come back on my next geneva stay!!
