Severin's place is very clean and perfectly accomodated to receive airbnb travelers. He is a nice host with good communication and on time. He also has a lot of books and maps for tourists and non tourists to learn more about the city and Switzerland and he is happy to share tips. Important thing to take into consideration for the trip's organization is that there is no access to the kitchen to do some cooking during the stay. If you don't need it then the flat is close to the center and 5 min walking to the train station.
