What works best for this apartment is it location and a very responsive and responsible host, Djamel. It made a difference for our one month stay there. Ideal for those who take courses in IMD or similar. Restaurants, supermarket, laundry services etc are all around. The lake is 7 mins away and rail station is 10 mins uphill. The kitchen is small but adequate for simple cooking. Toilet is good with bath tub.
The apartment like many in Lausanne is old but inside the apartment it's comfortable enough for 2.
