I stayed four nights in the Alpexpo, and it was good, however, not the best place I have ever been to.
I booked the room by email and there was absolutely no problem. They did not even request me to give them my credit card number and since I got a corporate price, it was quite cheap.
The room was spacious and I had a huge double bed. There was an LCD TV, phone and both wired and wireless Internet access (the latter two for additional charge.) The room, the bed linen and towels were clean, however, the bathroom needs serious remodeling and "mold removal".
Although the bathtub was more or less clean, it was very old and the bottom felt like a sandpaper when I stepped on it. Moreover, there was a wide mold line along the wall, and the whole bathroom looked like it has not been touched since the '50s.
Breakfast is the usual continental one but waaay better than the same in the US.
