I stayed at Stephane's place for a week while attending a conference at EPFL. I could not have asked for a better arrangement. The apartment is freshly remodeled throughout, sparkling clean, stylishly furnished, and thoughtfully laid out to feel spacious and welcoming. The kitchen is small and with everything you need to prepare simple meals--good knives, pots/pans, cutlery,/plates, microwave/oven, full size fridge, hot water kettle. The Nespresso machine is a nice touch! The bathroom is immaculate and the shower flow is strong with lots of hot water. :-) All the appliances/fixtures/furniture are new.
The space itself is bright and well-lit. Floor-to-ceiling windows fill the room with morning sunlight, and the back glass doors open up to a central yard/courtyard area where children play. Since the building and neighborhood feel safe, quiet and peaceful, the space was a great place to study/work. I enjoyed returning to it after long days at the conference.
10-15 min walk to EPFL and to the metro/grocery in Ecublens. East of the building complex is active farmland. In spring-fall there is a farmer's market 5 min away on Thursdays. If you run, there is a lovely dirt trail that goes for miles and miles along the Venoges stream, you can run all the way down to Lake Geneva or in the opposite direction for quite a distance through the forest.
Stephane was extremely helpful and responsive to my questions/requests and a pleasure to interact with. I am definitely going to come back for future visits to Lausanne!
