I went to Bansko with my family in March and we stayed in a lovely catered chalet called Chalet Jora. The snow was great, loads of powder and off piste tree runs that were easy to get in and out of from the main pistes.
The chalet was really comfy and cosy, we felt really at home there. The rooms are clean and nicely decorated and we were even given slippers to wear. We stayed on a fully catered basis which included breakfast, afternoon tea and 3 course evening meals. The food was excellent, very tasty and filling. We were given free wine with dinner and the fridge was always stocked with beer.
I'd definitely recommend Bansko and Chalet Jora to anyone thinking of a ski trip. The price was amazing for the quality of the chalet and the hosts were so friendly and welcoming.
