Gaëlle's apartment is in a fantastic location in St Sulpice. I stayed there for a conference held at the STCC, and it was easy to walk there. Good connection to Lausanne city centre via bus, a good view of Lake Geneva isn't far away—and Gaëlle is very helpful. She was especially hospitable in a situation where she had to juggle a lot for the week. Really well done, and a good place to come to!
