The apartment is very nice and spacious.
I had the bedroom to myself with a comfortable, proper single bed.
Mayeul was away, but you have to be prepared that you may also share the bedroom.
It is clean & tidy (the bedroom and the whole flat), really no issues or problem with anything.
It is also very close to a metro station (5 minutes easy walk) and also not far from the main railway station (walkable - but note it is hilly there).
A supermarket and Domino's Pizza is literally around the corner.
Very good value for money, i will definitely stay in Mayeul's place in the future visits to Lausanne.
