The building has different studios on different floors. We were given a studio very close to the entrance on the ground floor that had paper-thin walls and door so we could hear everything that was going on on the stairs, from people entering and being loud during the night to people leaving early in morning (5 am). Next to the entrance and outside of our room there is some sort of a utility unit that is producing a rumbling sound, which is also not beneficial to a good night's sleep. I read that most of the people had left very positive reviews and only one person said that the studio was very loud. So probably studios on higher floors are more insulated or anyway further from the entrance of the building and therefore less noisy. I would not recommend this studio if you want to relax and have some peace during your holidays in Lausanne.
