Communication was very easy! Séverine was always quick to respond to inquiries. They were very accommodating from beginning to end. If you’re visiting CERN this is an excellent place to stay. I suggest to walk there as it is less than a mile. It’s also a great way to see the shops around. It is also a very quick tram ride to the city center of Geneva. And the yurt itself was very tidy and there’s more than enough heat to make it cozy. Excellent stay!
