Staying at Julia's apartment was great and she was very helpful in organizing move in late in the evening.
Her flatmate Flavie, was there and very helpful and kind throughout my stay.
The room was simple and nice and had a balcony next to it. The apartment was duplex and during the nice cool weather days it was lovely.
The apartment is pretty central in Lausanne and a few mins walk from Lausanne chauderone and the M1 Vigie stop.
