The unit is located at the old town part of Montreux which is very scenic and quaint. It took us about 15 minutes to walk from the main train station (take the Golden-Rail exit which is at the other side of the station). Not an issue unless you carry large suitcases which you'd be better to take taxis which are plenty outside the train station.
Check in was easy for us as Vincent & Julien provided clear direction. The unit is on the 2nd floor of a building so it is not suitable for people with disability. The unit itself is smaller than I initially imagined but it fits well for our family of three (me + wife + 19 year old son). The unit comes with a full kitchen and a washer/dryer is available at the basement which has a separate access from outside the building. There are a queen size bed and a full size bed inside the unit and the beds are comfortable. WiFi is available and good. When we checked in, we found bottled waters, soft drink, beers and chocolate in the fridge prepared by Vincent & Julien which we really appreciate the nice gesture.
It also takes about 15 minutes of easy walk from the unit to the center of Montreux. There is a small neighborhood grocery store and a couple of cafe/Tea Rooms nearby. I recommend future guests to try the "Tea Room in Baye, Chez Monique and Jacques" which is about 50 meters from the building towards city center/train station. The owner is very friendly and she made delicious croissants and quiches. Overall we had a wonderful stay at this place.
