Staying with Severine was a delight! She made us feel at home straight away and was incredibly inviting and helpful.
The yurt is ideal for short stays and was very unique. It is not too hot or cold in the night and it is not noisy either. A few things you should know before booking (which is probably mentioned in the Airbnb page anyway):
1) There are dogs on the premises but they are very friendly
2) The toilet has no water, so you have to use sand
3) No shower in the bathroom
4) No WiFi
That being said, I would thoroughly recommend the yurt if you want to have a fantastic holiday in Geneva!!
