This is a comfortable and conveniently-located hotel just blocks from downtown Chamonix. What we liked: AMAZING breakfast spread (but not cheap), clean, all the staff were very nice, pool (what a view!) and the location. What we didn't like: the concept, while interesting, didn't work for us. There were no quiet places to just sit and read outside of our hotel room (which had no chairs, just the bed) and when we did decide to grab a drink or pizza on the patio, the music was abrasive. It would be fine if it was just one- but you can both hear a DJ playing loud music outdoors and also the indoor performances of their (very talented and under-appreciated!) dancers. The combination of the two was just obnoxious and I'm really surprised nobody at the hotel has noticed and addressed this.
We also had a mishap with a couple items that had been sitting on the bed (there aren't many spots to put things in these rooms, they're small!) getting taken away with laundry when housekeeping came by. It took three different people and 24 hours to, thankfully, get our belongings back (this was not a language barrier issue, I speak fluent french). Major credit to the person who finally did, he was very kind, but this was quite stressful and made all future housekeeping dates anxiety-producing.
Overall - if you're traveling here with a bachelor/bachelorette party, or with young kids, this is probably a great choice. Otherwise, consider looking elsewhere.
