The location is the most valuable thing.
It was a very optimal location, about 200m from the heart of Chamonix, in front of the train station.
The housekeeping was very good and the rooms were very nice but I would have liked to have a mini fridge. However, the shower drain wasn’t working properly and the bathroom flooded every time we showered.
The staff was not very friendly. Some of them didn’t speak French and wouldn’t try to either. Others the same with English. The breakfast was very disorganized and nobody was cleaning the tables or refilling the food.
The elevator was broken so we had to go up and down everyday. The day we left, I had a family member go down and ask for help with the luggage because we were in the fourth floor and someone did help us but with a bad attitude.
That was quite disappointing.
If you care greatly about location, this is your place. Beware though, not great service.
