Dear Yassine, Greetings from Montreux. Unfortunately, as this particular property which you booked is family accommodation only, we cannot accommodate groups of friends, who are coming to have a party and with the intention of making loud noise. Based on our policy, and mentioned on our listing, parties are not allowed. We do have other properties in Montreux and also Interlaken, luxury holiday apartments, which can accommodate groups of friends, on acceptance of the policies and local regulations for noise and respect of both the neighbours in the residence, and the local commune quiet times. We look forward to welcoming you soon and send you, our best wishes.
