We had a week in mid january. The location of the apartment in ideal for access to the gondola, especially at the end of the day when you are tired! also there are a number of bars and restaurants that are very close.
The apartment is ideal, very warm and comfy, the complex is ideal to having the pool, sauna, steam and jacuzi only a few minutes walk away.
The skiing is great, was my first ski for far to many years, the instructor was great and soon had you confident on the slopes.
The people in bulgaria are very friendly, and never felt awkward as can happen. Obviously one of the great things about the place is the cost, it is so well priced when you go out.
