Having lived in the apartment for a month, I can fairly say I know the apartment well. Anne-Sophie and Guillermo have hospitality in their blood and will make sure their guests have a pleasant stay.
The apartment is spacious, very clean, well maintained and equiped with a small kitchen, tv and wifi. The location is also ideal. Being close at the highway it can be reached by car very well and makes trips to the surrounding area very easy. And the tram at the end of the street brings you to the city center within 20 minutes.
I can recommend this apartment to anyone who wants to have a pleasant stay in Geneva.
