Staying at Abraham's apartment was a great experience! I felt very welcomed and almost like at home. The apartment is very modern, tidy and clean and provides everything you need (big kitchen, your own bathroom, and a comfortable queen size bed). With the bus you only need 10 minutes into down town- by foot around 25 minutes. Lausanne is on a hill, therefore walking can be exhausting. I took the PubliBike for a ride along the lake, which I recommend a lot!
