Being that it is rated as a 4 star hotel, I had certain expectations when arriving at this hotel, but was sorely disappointed thereafter. First of all, the hotel is like being stuck inside a small chimney!! The staff does not take any measures to separate the non-smoking guests from those who smoke. Not at the restaurants, the lobby, even the rooms, although they claim to have "non-smoking rooms" available for guests who request it. I requested one, but it was clear after the first few hours that they had put me in a smoking room, and I could still smell the smoke in the air from the previous guests. Being that the common areas are not ventilated, especially during winter, it truly was like being inside a chimney all the time...
Also, they charge you for EVERYTHING. The hotel doesn't give you any real curtesy amenities, for example, if you ask for an iron, they have one, but they'll charge you for it. A pair of socks, no matter how small, will cost you at least 4 CHF to have them washed in a washing machine, etc.
There are better and less expensive hotels in Davos, and I recommend looking into those first.
