In reply to Axel Smeets:
We went there several years ago, chosen because it was the cheapest deal we could find, and we thought Bulgaria might be more interesting to visit than France.
We were somewhat shocked on the first night to discover the place was something of an Ibiza on Ice with all the bar owners offering free shots to get you into their bar and prostitutes in the lobby of the largest hotel!
However after the initial shock we had a fantastic holiday, I was in Ski School and had a great instructor who spoke good English. Our Hotel was lovely and comfortable, the food was fine, the alcohol was cheap and everyone was very friendly.
The infrastructure is not up to the standard you would expect in France/Switzerland etc, but everything worked fine.
Our favourite bar/cafe was White Mountain (I think), the owner was an ex ski champion and very friendly. As well as owning the bar he does a bit of filming on the side so we had our lesson videoed one day which was very funny and a great souvenir.
