We went to montreux during the mountreux jazz festival, and the apartement was located perfectly! Only a 5 min. walk down to the festival. Such a great view right outside of the apartement as well!:)
Veronique was easy to reach, and the communication was good.
I would suggest buying a fan if it is very warm during the stay, but she also had a sofa that could turn in to a bed downstairs, where the temperature was perfect:)
I would definitely live here again and recommend this place!:)
