I stayed at Carmen's place for one week. I really had a great time and enjoyed the stay there. That is the best Airbnb stay I have ever had! Carmen, Quentin and Adelaïde are very nice and friendly! They kindly welcomed me though I arrived late at night. The room is very big, clean, bright, comfortable and well equipped! I could freely access the kitchen, living room and bathroom, and found everything I needed. The apartment is next to a park and at walking distance from EPFL and UNIL. It is well connected with the city center through buses and metro. I definitely recommend this apartment!
