Chose a tour with a guy for the New Year "Bulgarians are waiting for skiing" from Stagecoach Travel, because they were surprised that Bulgaria has not only the sea but also ski resorts. Went to the resort of Bansko. We had a hard time moving, we drove a long time, but the bus was comfortable, we were lucky that our group was small and there was plenty of space.
We went to this hotel on New Year's Eve, we were satisfied. We had a very warm room, you can even say the heat was in the room, it was clean, tidy, although the shower was leaking a little, but these are trifles.
