I stayed 3 months in this apartment.
it is very central, i was was walking to the Lausanne central station and the old city center ( 15-20 mnts walk).
the appartement is very functional for 1 or 2 people, there is everything you need.
nice rooftop terrace.
the owner Waleed was extremely helpful and supportive for any questions or requests.
definitely i recommend it for short or mid term stays.
